The fallout from the Syrian air strikes continues to dominate the front pages on Monday, as Theresa May prepares to face Parliament over her decision to authorise the action.
Mrs May will tell MPs it was in the national interest to launch the strikes, and was aimed at preventing human suffering, The Guardian reports.
The i predicts a "House of Commons showdown", and reports that some Tory MPs fear Britain could be dragged further into the Syrian war, while the Metro says Labour leader Jeremy Corbyn will confront the PM after claiming Donald Trump's tweets convinced her to join the operation.
Mrs May has issued an ultimatum to MPs to back the military action or expect more chemical weapons attacks by the Assad regime, the Sun reports.
The paper carries a column by the PM, in which she says she was "absolutely certain that it was the right and legal thing to do -- and at the right time".
Meanwhile, several papers warn retaliation from Russia could be imminent, in the form of a cyber attack.
The Daily Mail reports that intelligence officers at GCHQ and the Ministry of Defence are on standby to hit back if the Kremlin does wage cyber warfare.
The Daily Mirror warns hackers could hit the NHS or transport, while the Daily Express says an attack could bring the UK to a standstill.
The Daily Telegraph reports that Whitehall sources confirmed a 20-fold increase in "disinformation" being spread by Kremlin-linked social media "bot" accounts since the strikes.
Elsewhere, The Times leads on a story about people being given personal NHS budgets to organise their own care, while the Financial Times follows up on the resignation of WPP chief executive Sir Martin Sorrell, saying a lack of a non-compete agreement means he is free to start a new advertising venture.
There is some good news on the front of the Daily Star, which suggests temperatures could soar to 26C in Britain this week.
