The Papers: 'Blood on their hands' and 'Starmer warns Iran'

Several of Tuesday's newspapers lead the day with the discovery that a doctor warned three years before the Nottingham attacks that Valdo Calocane's mental illness was so severe he could "end up killing someone". The Daily Mail focuses on the response of the "furious" families of the victims, who are quoted as saying that medics and police have "blood on their hands".

"They knew for three years he was a danger," the Metro declares in its story on the Calocane medical report. It reports that breaking into a neighbour's flat was "among a litany of missed chances to intervene" before he carried out the fatal attack in June of last year.

The Daily Telegraph leads with a warning from UK Prime Minister Sir Keir Starmer to the Iranian government against an escalation with Israel. In a "rare telephone call" with Tehran on Monday night, the paper says Sir Keir told Iranian President Masoud Pezeshkian that "there was a serious risk of miscalculation and urged Iran to refrain from attacking Israel". In other international news, the Telegraph also reports that Ukrainian President Volodymyr Zelensky "has piled pressure on Britain to allow missile strikes deep inside Russia" as Ukrainian troops claim to control a slice of Russian territory on the border.

The latest from Ukraine leads the Times, covering Mr Zelenksy's warning to Vladimir Putin that the war was "coming home" to the Russian president. The attack has been the largest incursion on Russian territory in more than two years of war, the Times reports, prompting Mr Putin to claim it was intended to “intimidate society and to undermine stability".

The Guardian's top story covers a climate study that suggests hot weather "inflamed by carbon pollution" killed nearly 50,000 people in Europe last year. The paper reports that the toll would have been "80% higher if people had not adapted to rising temperatures", which it says shows that "efforts to adapt societies to heatwaves had been effective". Beside that report is a photo of British Olympic diver Tom Daley, who has announced his retirement from the sport.

The Financial Times leads its Tuesday edition with Indian billionaire Sunil Bharti Mittal's acquisition of a 24.5% stake in British telecom giant BT. The investment is a "vote of confidence in the telecoms group and the UK", the paper quotes Mr Bharti as saying, praising BT's "glorious past", "national status" and "tremendous" infrastructure.

The Daily Mirror also features the disclosure of the Nottingham attacker's medical history as its top story, reporting the victim's "families' anger and calls for a public inquiry". Also covered by the tabloid are the latest additions to Strictly Come Dancing's 2024 line-up as Sam Quek, Nick Knowles and Paul Merson join the programme.

Rising tensions in the Middle East take the top story slot in the i, as the paper reports that it has learned of a UK plan to "airlift British nationals from across Middle East if Iran retaliation on Israel triggers wider regional conflict". Citing Whitehall sources, the i reports "significant concerns" about escalations, but that there is hope that "Iran will rely on show of strength".

Comments from Shadow Home Secretary James Cleverly lead the Daily Express, telling the government to "get a grip and fast" or the Channel migrant crisis will escalate. The front page of the paper also features the Nottingham attack latest and a farewell to Tom Daley, reporting that the "teary Olympic hero retires from diving".

It's an "invasion of the angry, drunken German wasps", the Daily Star reports, warning picnic lovers to beware of "millions of invading German lager-lout wasps looking for a bit of mindless aggro".
