A manhunt is under way after a US politician and her husband were shot dead in their home in a “politically motivated assassination” – and another politician and his wife were also shot.

Minnesota state representative Melissa Hortman and her husband were killed at their home, Tim Walz, the governor of Minnesota, confirmed.

State senator John Hoffman and his wife were also shot in their home but are expected to survive. The senator, according to officials, is in a stable condition after emergency surgery.

Authorities have confirmed that the suspect they are looking for is 57-year-old Vance Boelter – who, in a press conference, was described as a 6ft 1in white male, with brown hair and brown eyes.

Members of the public have been urged not to approach him as he may be armed.

The suspect was reportedly posing as a police officer, and officials said the alleged attacker escaped after an exchange of gunfire.

Both politicians are members of the Minnesota Democratic-Farmer-Labor Party.

US President Donald Trump, in a statement, said: “I have been briefed on the terrible shooting that took place in Minnesota, which appears to be a targeted attack against State Lawmakers.

“Our Attorney General, Pam Bondi, and the FBI, are investigating the situation, and they will be prosecuting anyone involved to the fullest extent of the law.

“Such horrific violence will not be tolerated in the United States of America.”

Authorities have urged residents of the Champlin and Brooklyn Park areas to stay in their homes.

In an earlier Facebook post, Mr Walz said: “I’ve been briefed this morning on an ongoing situation involving targeted shootings in Champlin and Brooklyn Park.

“The Minnesota Department of Public Safety and local law enforcement are on the scene. We will share more information soon.”

At a subsequent news conference, Mr Walz said: “We must all, in Minnesota and across the country, stand against all forms of political violence.

“Those responsible for this will be held accountable.”

He has also urged those in Minnesota not to attend political rallies until the suspect is caught.

Police evacuated the Texas State Capitol and grounds in Austin ahead of an anti-Trump protest on Saturday – citing a credible threat to politicians.

Post-mortem examinations will be conducted to determine the extent of their injuries.

However, it is clear that both Ms Hortman and her spouse died from gunshot wounds, Drew Evans, superintendent of the Bureau of Criminal Apprehension, said.

Ms Hortman, a mother of two, was first elected in 2004 – and was the top house Democratic leader in the state legislature. She also served as speaker of the Minnesota House of Representatives.

Mr Hoffman, also a Democrat, was first elected in 2012 – and ran a consulting firm called Hoffman Strategic Advisors.

Hakeem Jeffries, House Democratic leader, has described the shootings as “deeply disturbing” on X, adding that “violence is never acceptable”, and that he is “praying hard” for the victims.

Former Arizona representative, Gabby Giffords, described her friend Ms Hortman as a “true public servant”, who “dedicated her life building a better, safer Minnesota”.

Nancy Pelosi, former speaker of the US House of Representatives, said she was “heartbroken” by the news.

She added: “Unfortunately, we know the tragedy of when political violence hits home very well.

“All of us must remember that it’s not only the act of violence, but also the reaction to it, that can normalise it. This climate of politically-motivated violence must end.”

In a tribute, Democratic National Committee chair Ken Martin said: “Melissa, Mark, John, and Yvette – these are not just names, and this is not just politics.

“These are people. They’re longtime friends to me and Jenn and so many others in Minnesota. They have children, loved ones, neighbors, and friends.”

Mr Martin added: “Today, we recommit ourselves to fight harder for the values that Melissa and Mark embodied – building a kinder, more just, and loving world. If this murderer thinks we will be silenced, he’s wrong.”

US President Donald Trump has revealed details of a one-hour phone call with his Russian counterpart, in which they agreed the conflict between Israel and Iran should end.

Posting on his Truth Social platform, Mr Trump added that he told Vladimir Putin that “his war [in Ukraine] should also end”.

Iran has retaliated following Israel’s attack on its nuclear sites on Friday – which killed senior army officers and nuclear scientists.

The Iranian response has resulted in at least three people killed and dozens of injuries in Israel, according to medics. Iranian state TV, meanwhile, has reported that 20 children are among the 60 killed in a strike on a Tehran neighbourhood on Saturday.

Iranian missiles were seen entering Israeli airspace on Saturday evening.

Meanwhile, RAF jets and military assets are being sent to the Middle East after Tehran warned the UK and other allies their regional bases would be targeted if they helped defend Israel in the growing conflict between the two heavily armed countries.

In his post, Mr Trump said: “President Putin called this morning to very nicely wish me a Happy Birthday, but to more importantly, talk about Iran, a country he knows very well. We talked at length.

“Much less time was spent talking about Russia/Ukraine, but that will be for next week. He is doing the planned prisoner swaps – large numbers of prisoners are being exchanged, immediately, from both sides.

“The call lasted approximately 1 hour. He feels, as do I, this war in Israel-Iran should end, to which I explained, his war should also end.”

Kremlin aide Yuri Ushakov said President Putin condemned Israel’s military operation in Iran and expressed concerns about the risk of escalation.

During the conversation, the Russian leader briefed President Trump on his recent talks with the leaders of Israel and Iran – reiterating Russia’s hopes to seek mutually acceptable solutions on Iran’s growing nuclear issue.

Meanwhile, the latest round of US-Iran nuclear talks scheduled for Sunday in Muscat will not take place, a senior US administration official has told Sky’s US partner network NBC News.

However, the official said the US is “not shutting the door to future discussions”.

“While there will be no meeting on Sunday, we remain committed to talks and hope the Iranians will come to the table soon,” the official said.

A parade marking the US Army’s 250th anniversary – and President Trump’s 79th birthday – is under way.

You can watch the event in the livestream above.

President Trump said it was going to be a “big day” and admitted: “We want to show off a little bit.”

Today is the first time in more than 30 years that tanks have rolled through the US capital.

Officials have estimated around 200,000 people could turn out, including protesters, plus 6,600 soldiers, 150 vehicles and 50 aircraft.

However, it appears far fewer have turned out – possibly due to the poor weather – and the president has warned any protesters who interfere “will be met with very big force”.

Mr Trump is watching alongside the first lady and defence secretary as troops and military hardware file past – accompanied at times by up tempo rock music.

The event started half an hour early due to forecasted heavy rain, with cloud forcing the cancellation of a flypast by fighter jets.

Helicopters such as Apaches, Chinooks and Black Hawks are still taking part however.

Military parachutists from the Golden Knights began the parade by swooping in, and some of the soldiers are parading in historic uniforms, complete with horses and wagons.

Vehicles from the Second World War era are also taking part.

President Trump stood and saluted many of the passing soldiers. He is said to have got the idea for the parade after being impressed with France’s Bastille Day celebrations during a visit in 2017.

Metal plates have been put down on some of Washington’s streets to protect the tarmac against the heaviest tanks – the 60-ton M1 Abrams.

Even so, the US Army has set aside several million dollars in case of any damage.

The last time such a major display took place in the US was 1991 when tanks and troops paraded to celebrate the ousting of Saddam Hussein’s army from Kuwait.

The event has been criticised by some for being something more associated with a dictatorial regime such as Russia or North Korea.

An estimated cost as high as $45m (£33.33m) has also raised eyebrows given the administration’s efforts to slash the budget of many federal departments.

Among the critics is California governor Gavin Newsom, who has been trading barbs with Mr Trump since the outbreak of riots in LA.

“And we all know, this Saturday, he’s ordering our American heroes – the United States military – forcing them to put on a vulgar display to celebrate his birthday, just as other failed dictators have done in the past,” he said.

The show of military might also comes as more than 1,500 protests against the Trump administration, organised under the slogan ‘No Kings’, have been planned across the US on Saturday.

Los Angeles is the scene of one demonstration, with police firing tear gas to disperse people and US Marines stationed outside the city’s federal building.

Tension is high in America’s second-biggest city after recent raids by immigration officers sparked unrest this week.
