Newspaper headlines: 'Iran war' fears and 'two more teens killed'

People in Bristol took part in a vigil to remember the two boys stabbed-to-death

The killing of three US soldiers in Jordan in a drone strike prompts warnings on several front pages.

The Guardian says the spectre of direct US-Iranian military conflict has drawn closer. The Daily Telegraph quotes a US official as saying the attack is clearly an escalation of significance, while the Financial Times says America is likely to be pulled further into a conflict, even as Washington seeks to avoid a broader regional conflict. The Daily Mail highlights comments from two Republican senators who directly call for the US to target Iran.

On its front page, Metro features a picture of the police cordon in Bristol where two teenagers were killed in a stabbing on Saturday night. "Two more teens killed in UK knife 'epidemic'" is the paper's headline. The Guardian has a photograph of mourners gathered for a vigil near where the stabbings happened. The paper quotes one woman who witnessed the aftermath of the attack as saying "I can't get it out of my head".

"Strike hell on trains as chiefs cash in" is the Daily Mail's front-page headline. The paper says rail bosses have been pocketing "huge bonuses and pay rises" - but are not enforcing new laws to minimise the impact of strikes. It says none of the operators affected by industrial action this week has implemented the requirement to provide at least 40% of normal services. The Rail Delivery Group tells the paper that although the measure is useful for managing disruption, "it is not a silver bullet".

The i leads with concerns Labour's pledge to charge VAT on private school fees could make it harder for some children to get into state-run grammar schools. It says senior figures in education are worried children from deprived backgrounds could lose out on places. One headteacher tells the paper private school parents are "best placed to be buying houses right next to the schools".

"Lives wrecked by Tories town hall cash squeeze" is the headline in the Daily Mirror. The paper says vulnerable people are being hit by cuts to councils with 40 on the brink of effective bankruptcy. Its front page pictures an 81-year-old man with dementia whose care home is closing.

"Balmy" declares the Daily Star as it highlights the sudden turn in the weather. "Britain's 19.6C January heat record... days after shivering in arctic blast" is the paper's headline. "Highland spring" proclaims the Daily Express, which carries a picture of a sun soaked Scottish mountain near Kinlochewe, where the temperature was recorded. It says the area was warmer than Rome and the French Riviera.

Many of the sports pages celebrate England's win over India in the first Test in Hyderabad. Writing in the Telegraph, the former England captain, Michael Vaughan, calls it "the finest England Test victory" of his lifetime. The Sun describes it as a "mind-blowing triumph". The Guardian says England supporters at the match were "close to a state of nirvana". The performance of the spin bowler, Tim Hartley, is also recognised after he struggled in the first innings and then took seven wickets. "Debut goes from hell to seventh heaven", says the Daily Mail.
