Escalating tensions over the crisis in Syria continue to top the news agenda - with Russia accusing Britain of staging the suspected chemical weapons attack.
The situation has reached "boiling point", warns the Daily Mail, which reports that Theresa May was last night locked in a "face-off" with Vladimir Putin.
Mrs May cited the Salisbury poisonings as evidence that the 100-year taboo on chemical weapons was being eroded, the paper adds, as Moscow responded by warning against a repeat of Tony Blair's "reckless military adventure" in Iraq.
The Guardian says the deteriorating relations prompted United Nations Secretary-General Antonio Guterres to declare "the cold war is back with a vengeance" - words which the i describes as a "chilling warning to the world".
According to The Sun, Britain was last night "within hours" of launching air strikes on Syria, running with the headline: "War on the Gasman".
The paper adds that the PM has vowed to hit back at Bashar Assad to ensure there is no return to the horrors of the First World War.
The Times claims senior British academics are spreading pro-Assad disinformation promoted by Russia at universities in the UK.
Meanwhile, the Daily Telegraph takes a different angle on the tensions between the UK and Russia, reporting how Mrs May released declassified intelligence on the Salisbury attacks to quash the "disinformation" campaign by Moscow.
The files revealed that Russian agents had been hacking Yulia Skripal's emails for at least five years before the poisonings, the paper adds.
Elsewhere, the Daily Mirror leads on the pensioner who fatally stabbed a burglar, reporting that he is so scared for his safety that he must move house.
And both the Daily Star and the Daily Express lead on Sir Cliff Richard's ongoing court battle against the BBC.
