Vladimir Putin has claimed the gunmen behind the Moscow concert hall terror attack attempted to flee to Ukraine in the aftermath of the mass shooting.
The allegation, made by the Russian president during an address to the nation, came despite the Islamist terror group Islamic State Khorasan (IS-K) claiming responsibility for Friday night’s attack, in which at least 130 people were killed.
Ukraine strongly denied any involvement in the shooting, which comes two weeks after the US shared intelligence with Russian security officials warning that “extremists” had imminent plans for an attack in Moscow.
In an address to the nation on Saturday, Mr Putin described the shooting as a “bloody and barbaric terrorist attack”.
He also claimed that Russia had intelligence which suggested Ukraine had prepared a “window” to allow the gunmen across the Ukrainian border.
“All four direct perpetrators of the terrorist attack, all those who shot and killed people, were found and detained,” Mr Putin said.
“They tried to hide and moved towards Ukraine, where, according to preliminary data, a window was prepared for them on the Ukrainian side to cross the state border.”
He also declared Sunday as a day of mourning and said those responsible could “expect only one thing, they can expect punishment”.
On Saturday afternoon, officials in Russia said at least 133 people had died in the attack on the 6,000-capacity Crocus City Hall, in the western Moscow suburb of Krasnogorsk – making it the second-deadliest single terror attack in Russia’s history.
As concert-goers gathered in the hall, the four men, armed with Kalashnikov automatic weapons, arrived in a minivan and walked calmly towards the metal detectors, before opening fire on civilians, often at point-blank range.
Russian investigators said the men began to set fire to the building during the shooting.
Hours later, IS-K, a regional branch of the Islamic State militant group operating in Central Asia and Afghanistan, claimed responsibility for the attack.
The group’s Amaq news agency said on the social media site Telegram that the attack came “within the context of a raging war between the Islamic State and countries fighting Islam”.
Central Asia is a fertile recruiting ground for IS-K, as are the restive republics of the Russian Federation, Ingushetia, Dagestan and Chechnya.
The group claims Mr Putin and his regime are killing Muslims and have previously pointed to Russia’s military operations in Chechnya, Syria, and Afghanistan.
Russia’s interior ministry said all four of the gunmen were foreign nationals, but did not specify which country they were from.
Some of the suspects were shown being interrogated on the side of the road in footage published by Russian media and Telegram channels with close ties to the Kremlin.
Russian media said the men had fled the scene in a white car and that the men were detained in the Bryansk region, about 210 miles (340km) southwest of Moscow.

Following the attack, two anonymous US officials said Washington had intelligence confirming Islamic State’s claim of responsibility.
They also said the US had warned Russia in recent weeks about the possibility of an attack – ahead of the US embassy in Moscow issuing a warning to Americans in the city.
Islamic State Khorasan (IS-K) has taken credit for attacks by other terror networks in the past, but it is almost certainly behind the deadly assault in Russia, though nothing is impossible.
The group has claimed responsibility, and the chatter picked up by Western intelligence services in the days leading up to the atrocity also indicated something was coming.
The number of people killed in Friday’s shooting near Moscow is grim and likely to keep climbing.
Many people presumed Islamic State (IS) had been neutered, but it has been growing in strength in recent years, particularly IS-K.
“We did warn the Russians appropriately,” one of the US officials said.
Ukrainian military intelligence spokesman Andriy Yusov, meanwhile, denied any Ukrainian involvement.
“Ukraine was of course not involved in this terror attack,” he told Reuters.

Why would Islamic State attack Russia?
Mykhailo Podolyak, an adviser to Ukrainian President Volodymyr Zelenskyy, also said on X: “Ukraine has never resorted to the use of terrorist methods.
“Everything in this war will be decided only on the battlefield.”
Meanwhile, Ukraine’s foreign ministry accused Moscow of using the attack to “further fuel anti-Ukrainian hysteria in Russian society”.
“We consider such accusations to be a planned provocation by the Kremlin to… create conditions for increased mobilization of Russian citizens to participate in the criminal aggression against our country and discredit Ukraine in the eyes of the international community,” the ministry said in a statement.
A helicopter carrying Iran’s president has been involved in a “hard landing” during bad weather, Iranian state media has said.
President Ebrahim Raisi was travelling across the far northwest of Iranfollowing a visit to Azerbaijan.
Rescue teams are trying to reach the scene but are reportedly being hampered by fog and heavy rain in a mountainous area.
State media initially said it happened near Jolfa, about 375 miles (600km) northwest of Tehran, but then put it further east near the village of Uzi.
The president was said to be travelling with foreign minister Hossein Amirabdollahian, the governor of East Azerbaijan province and other officials.
However, Iranian interior minister Ahmed Vahidi didn’t confirm whether Mr Raisi was on board the helicopter involved, saying he was travelling in a convoy of three aircraft.
Mr Raisi had been in Azerbaijan for the inauguration of a dam with the country’s president, Ilham Aliyev.
“The esteemed president and company were on their way back aboard some helicopters and one of the helicopters was forced to make a hard landing due to the bad weather and fog,” the interior minister said on state TV.
“Various rescue teams are on their way to the region but because of the poor weather and fogginess it might take time for them to reach the helicopter.”

He added: “The region is a bit [rugged] and it’s difficult to make contact. We are waiting for rescue teams to reach the landing site and give us more information.”
Many of Iran’s military aircraft date back to before the 1979 revolution and international sanctions can make it hard to obtain parts.
Mr Raisi, 63, is a hardliner and former head of the judiciary who some have suggested could one day replace Supreme Leader Ayatollah Ali Khamenei.
He was elected in 2021 at the second time of trying.
Mr Raisi’s time in charge has included major protests over Mahsa Amini – the woman who died after she was arrested for allegedly not wearing her hijab properly.

Officials in Slovakia are investigating whether the attacker who shot the prime minister was not a “lone wolf”.
The interior minister Matus Sutaj Estok issued the update on Sunday, after the suspect was previously believed to be a “lone wolf”.
Robert Fico’s condition is no longer life-threatening but is still very serious, his team said on Sunday.
Deputy prime minister Robert Kalinak issued the update four days after the assassination attempt on the populist leader.
Speaking to reporters outside the Banska Bystrica hospital, where Mr Fico is being treated, he said: “The worst that we feared had passed, at least for the time being.
“We are all a little calmer. When we were saying that we want to get closer to a positive prognosis, then I believe that we are a step closer to that.”
The prime minister, 59, was shot multiple times on Wednesday in an attack that raised fresh concern over the polarisation of politics in the central European country of 5.4 million people.
Mr Fico was shot in the abdomen as he greeted supporters – the first major assassination attempt on a European political leader for more than 20 years.

Video footage showed the Slovak premier approach people gathered at barricades and reach out to shake hands as a man stepped forward, extended his arm and fired five rounds before being tackled and arrested.
Mr Estok has previously said the suspect objected to the government’s Ukraine policy.
Mr Fico’s government has ended official military support for Ukraine and taken a more pro-Russian line on the conflict than most European Union partners.

Slovak PM shooting suspect’s home raided
The Slovak Specialised Criminal Court ruled on Saturday that the suspect, identified by prosecutors as Juraj C, should remain behind bars until the trialcharged with attempted murder.
Prosecutors said they feared he could flee or commit other crimes if freed, a court spokesperson said.
The suspect can appeal the order, but so far no statement has been published by him or a lawyer on his behalf.
Little information about the would-be assassin has been made public, after prosecutors told police not to identify him or release details about the case.
Meanwhile, Mr Kalinak, who is also Slovakia’s defence minister, said Mr Fico’s condition was still too serious to consider transferring him to a hospital in the capital.
Milan Urbani, deputy director of the Banska Bystrica hospital, told reporters that, as of Sunday morning: “The patient is currently out of a life-threatening condition”.
He added: “His condition remains very serious, and he needs a long time to rest to recover. We firmly believe that everything will go in a good direction.”
Members of a Ukrainian brigade have described how they were secretly relocated to help defend a section of the country’s border with Russia a few days before a new invasion began.
The commander of an artillery unit from 57 Brigade said his guns were even firing at Russian troops the day before the ground incursion into the northeastern region of Kharkiv, which started on 10 May. He said the forces had been “brazenly” amassing on the Russian side of the border.
“We were hitting tanks on the border… it was already a real war,” said Sasha, 26, who uses the callsign “black”.
The commander of a second artillery unit similarly confirmed the brigade had been moved early to bolster defences in this direction.
The troops had previously been defending the city of Kupiansk, also in Kharkiv.
The comments offer a sense of how Ukraine attempted – ahead of time – to scramble forces to counter a Russian build-up along its long, northeastern border.
But the move was nowhere near enough to prevent the largest assault into Ukraine since Russia launched its full-scale invasion almost two and a half years ago.
A Ukrainian source, describing the first few days of the Kharkiv offensive just over a week ago, said there had been moments when he feared “we had lost the frontline”.
The source said the situation had since stabilised but warned: “We don’t know how long it could be like this”.

Sky News on Saturday tried to visit an artillery position, manned by soldiers from 57 Brigade, just outside the town of Vovchansk – a key target of the Russian offensive.
As we approached at speed by road, a soldier travelling with us said we had to pull over because he needed to communicate via radio with troops on the gunline.
Suddenly a voice over the radio could be heard saying: “Don’t come here. Don’t come at all.”
We were told it was too dangerous to travel further and we had to leave. It was not immediately clear what was happening on the ground.
At a makeshift base, safely back from the frontline, the artillery unit commander Sasha uses electronic maps on a tablet and laptop to confirm targets for his guns to attack.
He said he and his team relocated from the Kupiansk front on the 4 to 5 May.
“We were indeed moved here earlier,” Sasha said. But he signalled he would have liked longer to prepare.
“I don’t know all the situation and why it happened like this. But I know for sure that to better repel [an attack], we might need either more time or better-prepared positions,” he said.
“Ahead of the assault, we were already hitting targets on Russian territory because we knew they were gathering there. They were brazenly assembling.”
Sasha described the moment the Russians started to advance.
He said it began with three hours of artillery fire against Ukrainian targets before ground troops crossed the border.
“I would love that they [the Russians] had been stopped at the border,” he said.
Instead, a fierce battle erupted, as Russian infantry, backed by airstrikes, drone attacks and artillery fire, pushed forward.
“For the first few days, they [the Russians] were storming our positions – columns of 30 to 50 soldiers. We were hitting them.”
In the chaos, Sasha said he worked to gather information to ensure his troops were able to operate.
“I am proud that my guys managed to do their best,” he said. “All credit to those who stayed on their artillery positions.”
He described the frontline as initially being “fragile” but said reinforcements were now in place. The commander said Russia had lost the opportunity to make a significant breakthrough.
“Until now they had a chance. Even in my area, I knew where we had gaps where they could have slipped through. Now we don’t have such gaps,” he said.
“I am satisfied that we have managed to stabilise the situation.”
At a second artillery position, on a different section of a frontline that has expanded by some 40 miles in the wake of the new attack, a Soviet-era gun, hidden under netting and tree branches, points in the direction of Russia.
Soldiers here said they would be able to inflict a lot more damage on the invaders if they had more ammunition and better weapons.
Nicknamed “grandma”, their D-20 Howitzer artillery piece, which fires 152mm shells, was built in the 1970s.

“We’re saving our artillery shells right now. We fire one, they fire back five,” said one of the servicemen, who – at 50 years old – has the callsign “Grandpa”.
A second soldier said Russia has more weapons than his side.
Asked what difference additional munitions would make, he said with a laugh: “It would increase the number of dead Russians – 100%”.
