Alexei Navalny has become the latest in a string of deaths of critics of Russian President Vladimir Putin.
Over his more than two decades at the top of the Kremlin, a number of Mr Putin’s opponents have suffered unfortunate fates – including being jailed, shot dead in the street, or poisoned with tea spiked with polonium-210.
Who are the people who have dared speak out against Mr Putin or defy the Kremlin, and where are they now?

Alexei Navalny
Born to factory owners in a village west of Moscow, Alexei Navalny grew to become perhaps the highest-profile critic of Mr Putin’s time in power.
His political activism, including extensive investigations into high-level corruption and running to be mayor of Moscow, gained him fame – and many believed he posed a threat to Mr Putin.
It was in August 2020 when his fight against the Russian president hit the global headlines.
His team accused the Kremlin of poisoning him, a charge the Kremlin denied.
German medics confirmed that he had been poisoned with novichok – a Soviet-era nerve agent – and his recovery took months.
Despite the danger, Mr Navalny elected to return to Russia where he was later arrested, convicted on charges he says are politically motivated, and sent to a Russian penal colony.
Opposition politician Boris Nadezhdin declared that he would run against Mr Putin in the 2024 presidential election.
Despite doubts that the 60-year-old could present a serious challenge to the incumbent leader, Mr Nadezhdin said he had gathered more than 200,000 signatures from across Russia.
He had surprised some analysts with his strong criticism of what the Kremlin calls its “special military operation” in Ukraine, calling the war a “fatal mistake” and vowing to try to end it through negotiations.
On 8 February, he said he had been barred from running in the election and the Central Election Commission said it had found flaws in signatures his campaign had collected.
He vowed to appeal to Russia’s supreme court, adding: “Taking part in the presidential election in 2024 is the most important political decision of my life. I am not giving up on my intentions.”
Speaking to Sky News last year, Mr Nadezhdin said he was not afraid of speaking out “because I have a long life” and he had faced death several times.

Yevgeny Prigozhin
The ascension of Yevgeny Prigozhin from a hot dog seller to the boss of a private army which marched on Moscow was remarkable.
His Wagner Group mercenaries were notorious both for their brutality in Ukraine but also their influence in Africa.
Prigozhin became increasingly bold in his criticism of the Russian military and its top command.

When his forces began a march on Moscow from the southern city of Rostov it appeared to be the biggest challenge to Mr Putin for decades, but the apparent coup attempt fizzled halfway to the capital.
A former deputy prime minister of Russia under President Boris Yeltsin, Boris Nemtsov was a fierce critic of Putin and a prominent opposition leader.
He had been working on a report examining Russia’s role in the conflict in Ukraine in 2015.
But, aged 55, he was killed before it was finished. Mr Nemtsov was shot dead on a bridge just metres from the Kremlin as he walked home at night with his girlfriend.
Five men were found guilty of organising and carrying out the contract killing. Zaur Dadayev, an officer in Chechen leader and Putin ally Ramzan Kadyrov’s security forces, was found guilty of firing the fatal shots.
The Kremlin denied involvement in the killing.

Alexander Litvinenko
A former agent with the Russian FSB security service, Alexander Litvinenko fled Russia and eventually gained British citizenship.
He had accused Mr Putin of corruption and also blamed him for the infamous Moscow apartment bombings which Mr Putin, then prime minister, had used as a reason to start the Second Chechen War in 1999. It proved hugely popular and helped bring him to power.
The poison was ingested during a meeting with two Russian spies at the Millennium Hotel in London and the killing is thought to have been signed off by Putin himself. Russia has always denied any involvement.
Garry Kasparov
Regarded as one of the greatest chess players of all time, Garry Kasparov has been living in exile in New York since 2013.
The former world champion had become an impassioned campaigner against Mr Putin’s rule and took part in some of the mass opposition street protests organised by Alexei Navalny.
Investigative journalist, Paul Klebnikov, an American of Russian descent, was killed outside his office in a drive-by shooting in Moscow in 2004.
He was the editor of Forbes Russia and had written about corruption.
Forbes had also published a list of the country’s richest people.

Natalia Estemirova
Natalia Estemirova was an award-winning human rights campaigner who had collected evidence of abuses in Chechnya since the start of the second war there in 1999.
She was kidnapped near her home on 15 July 2009 in the Chechen capital, Grozny.
Several hours later her body was found in an area of woodland, with gunshots wounds to the head and chest.
Then president Dmitry Medvedev rejected claims that Chechnyan leader Ramzan Kadyrov was responsible and suggested the killing had been carried out to discredit the Kremlin.

Denis Voronenkov
A former Russian politician, Denis Voronenkov was an outspoken critic of Mr Putin.
Previously a member of the communist faction in the lower house of Russian parliament, Mr Voronenkov fled to Ukraine in 2016 and was granted Ukrainian citizenship.
He was shot and killed in Kyiv in March 2017.
Ukraine’s then president Petro Poroshenko described his killing as an “act of state terrorism” by Russia – an accusation rejected by the Kremlin.

He made his fortune in Russia in the 1990s during the mass sell off of state assets following the collapse of the Soviet Union.
Once incredibly rich, in his later years his fortune is believed to have dwindled.
James Nixey, head of Chatham House’s Russia programme, previously described him as “the most virulently anti-Kremlin, anti-Putin of the oligarchs”.
“He was certainly willing to spend his money, what little he had left, in an attempt to use it to end the current regime in Russia.”
Mr Berezovsky was found dead at his home in Berkshire. An inquest recorded an open verdict amid conflicting evidence about the way his body was found hanged.

Sergei Skripal
Formerly a colonel with Russian military intelligence before leaving in 1999, Sergei Skripal went on to work at the country’s foreign ministry until 2003.
The Kremlin denied that Russia was in any way involved in the poisoning, describing British accusations that an attack had been approved by senior Russian officials as “unacceptable”.

Sergei Yushenkov
Liberal Russian politician Sergei Yushenkov was shot dead in a Moscow suburb in 2003.
A member of the State Duma and former colonel in the Soviet army, Mr Yushenkov was shot several times outside his apartment building.
He had been involved in setting up the Liberal Russia Party, which had achieved full registration just hours before he was killed.
Mr Yushenkov had been willing to speak out against Putin and the war in Chechnya.
The man suspected of shooting dead two Israeli embassy workers in Washington DC leaned over and fired at them repeatedly after they fell to the ground, the FBI has said.
Elias Rodriguez, 31, has been charged with murdering Sarah Milgrim and her boyfriend Yaron Lischinsky, after they left an event at the Capital Jewish Museum on Wednesday night.
Footage has showed Rodriguez, from Chicago, chanting “free, free Palestine” as he was arrested.
It later emerged Mr Lischinsky had bought a ring and planned to propose to Ms Milgrim.
Authorities are investigating the killings as both a hate crime against the Jewish community and terrorism.

Shootings suspect shouts ‘free Palestine!’
‘I did it for Gaza’
It comes as the FBI has said in a charging document on Thursday that surveillance footage shows how Ms Milgrim and Mr Lischinsky died.
Rodriguez is allegedly seen passing the couple after they left the museum before shooting them in the back.
The FBI says the footage then shows him leaning over the couple and firing at them several more times after they fell to the ground.
The video then shows Ms Milgrim attempting to crawl away before “(Rodriguez) followed behind her and fired again”, the charging document says.
The suspected gunman is then accused of reloading his weapon and firing at Ms Milgrim as she sat up.
According to the charging document, Rodriguez then jogged to the museum and once inside asked to speak to a police officer before stating that he “did it” and that he was unarmed.
He is then said to have told police: “I did it for Palestine, I did it for Gaza, I am unarmed.”

DC shooting: Father pays tribute to ‘perfect’ daughter
Suspect ‘expressed admiration’ for fatal protest
The court document also states that 21 expended 9mm bullet cases were found at the scene and the gun was slide-locked – meaning it was empty of ammunition.
An empty gun magazine was also recovered from the scene.
The FBI says it has obtained travel records which show Rodriguez flew from Chicago’s O’Hare International Airport to the Reagan National in Washington DC on Tuesday with the gun in his checked baggage.
Rodriguez had bought the weapon in the state of Illinois on 6 March 2020, according to the charging document.
The FBI has said that while Rodriguez was in custody he “expressed admiration” for a US Air Force member who set himself on fire in front of the Israeli embassy in Washington DC on 25 February 2024.

Starmer ‘on wrong side of history’
During a brief court appearance at the E. Barrett Prettyman Federal Courthouse in Washington DC today, Rodriguez was charged with two counts of first degree murder and with the murder of foreign officials.
He has also been charged with causing the death of a person through the use of a firearm and discharge of a firearm during a crime of violence.
Rodriguez was told he could face life in prison or the death penalty if he is found guilty.
He remained calm throughout the hearing, paying attention to the proceedings throughout and confirmed that he is asking the court to appoint an attorney on his behalf.
He will next appear at a federal court in Washington DC on 18 June.
Murdered couple ‘were perfect for each other’
Meanwhile, Ms Milgrim’s father, Robert, says he feared his daughter might be in danger when he saw news alerts of a fatal shooting in Washington DC.
Ms Milgrim’s mother Nancy opened a phone locator app and saw Ms Milgrim was at the Capital Jewish Museum.
“Shortly after that, the Israeli ambassador called us on my wife’s phone,” Mr Milgrim told Sky News’ partner network NBC News, fighting back tears.
He added that it was the ambassador who told them Mr Lischinksy had bought a ring and was planning to propose to Ms Milgrim.
“They were perfect for each other, he said.
Mr Milgrim continued: “They just brought us joy, and her memory, which is a blessing, will continue to bring us joy – but it’s not the same as her not being here.”
There are multiple layers to this shocking act of extreme violence.
The presence of the US attorney general at a midnight news conference is a clear indication of the Trump administration’s shock and swift reaction. Pam Bondi had already visited the scene of the attack.
The president himself was quick to comment on social media, calling it out as antisemitism and saying: “Hatred and Radicalism have no place in the USA.”

There will be immediate questions for the US authorities about the security of Israeli diplomats. The shooting happened in the downtown area of DC, not far from the FBI field office and the FBI headquarters.
The two victims are understood to be junior aides and so probably not considered particular targets. But the shooting will prompt a fresh look at diplomatic security arrangements.
A video has emerged online said to show the gunman calmly shouting “free free Palestine” as he was detained by museum security.

Tearful witness: ‘He shot this young couple’
Pro-Palestinian protests have been intense on college campuses, outside embassies and elsewhere; the Israeli embassy in Washington has been a particular focus of protesters.
Last year, a 25-year-old active duty US airman immolated himself in front of the Israeli embassy in Washington to protest the war in Gaza.
Israel’s diplomatic relations with close allies, including the UK, France and others, have become increasingly strained over the methods used in its continuing war in Gaza.

Authorities will also be braced for how this incident plays in the days ahead.
There will be a concern within the Trump administration that this man’s actions will be given some glorification in parts of society, mainly online, in the same way Luigi Mangione became not just infamous but famous for allegedly shooting dead a healthcare executive in protest of corporate greed.
Expect prompt condemnation from the White House of any such glorification.

There is also a deeply tragic twist to this shooting. The two young victims were a couple and were due to travel to Jerusalem in the days ahead to become engaged.
I’ve been in touch with contacts at the Israeli embassy where the entire team is in shock and reeling at the loss of two of their own on the streets of Washington.
Witnesses have told Sky News of the moments after a man shot two Israeli embassy staff members outside a Jewish museum in Washington DC.
Yaron Lischinsky and Sarah Lynn Milgram, a couple who were about to become engaged, were shot dead as they left the Annual Young Diplomats reception at the Capital Jewish Museum in the US capital.

Footage emerges of Washington suspect
The suspect, named as Elias Rodriguez by police, shot at a group of four people just over a mile from the White House and then chanted a pro-Palestinian slogan in custody.
The event organiser told Sky News she handed the suspect water, mistakenly believing him to be an “innocent bystander”.

Shooting suspect shouted ‘free Palestine’
Jojo Drake Kalin said the event was wrapping up when she headed to the lobby to find “commotion and a frenzy” but at that time, no one was aware two people had lost their lives.
“The gunshots were heard, so security started locking the doors and that is when I saw who I now know is the… murderer of this Israeli-Jewish couple,” she said.
Ms Drake Kalin didn’t find out until “much later” who she was actually talking to.
“I see him [and] he seems very distraught. I now understand it’s because he killed two people point-blank. [I] offered him water, he accepted,” she said.
“The second I’ve handed him water, he whips out his keffiyeh [a scarf] and yells ‘Free Palestine’ and then he’s subdued by the officers on scene.”
Ms Drake Kalin said the event was themed around “bridge-building” between Israeli and Palestinian communities.
She called it “painfully ironic” that someone came in with “such hate and destruction”, considering the event’s theme.

“A guy came up and… looked like [he had a] gun, I couldn’t tell what it was, but I heard it afterwards, the shots, and he shot this young couple,” he said.
“He ran inside and yelled something.
“It was terrible. It was terrible.”
Another eyewitness, Katie Kalisher, said it was around 9.07pm when she heard gunshots.
“Then a man comes in. He looks really distressed and people are talking to him and trying to calm him down,” she said.
“Eventually, he comes over to where I was and we were like, ‘Do you need any water?’, ‘Are you okay?'”
Ms Kalisher said the suspect asked her what kind of museum he was in and when she replied, “It’s a Jewish museum,” he said: “Do you think that’s why they did this?”
She told him she didn’t think so but he then reached into his bag and pulled out a keffiyeh.
“[He] says, ‘I did it. I did this for Gaza’ – and just starts shouting ‘free Palestine’ and that’s when the police came in and arrested him,” said Ms Kalisher.
The reaction to the shooting has been one of shock, with President Donald Trump condemning the “horrible killings” which he said were “based obviously on antisemitism”.
Israeli Prime Minister Benjamin Netanyahu said his heart ached for the families of the victims, “whose lives were cut short in a moment by an abhorrent antisemitic murderer”.
