Newspaper headlines: '22 minutes of horror' and new prostate cancer hope

Tuesday's sword attack in northeast London was the focus of most front pages

Several front pages focus on Tuesday's sword attack in northeast London, including The Guardian, which has the headline "22 Minutes of Horror". It says detectives are "urgently" investigating why the suspect went on a "rampage", killing a 14-year old boy and wounding four other people.

The Telegraph reports that the incident was "captured on social media in almost real time by witnesses", and says that the teenager who died was targeted at random on his way to school.

A witness told The Mirror: "I can't stop envisaging his face."

The Sun expresses says the family's loss is "horrific and unimaginable" before going on to salute what it calls the "immense courage" of the police officers who tackled the suspect. Were it not for them, it says, "we might be mourning multiple deaths".

The Express argues that "every" member of the UK's police forces should have the means to, in its words, "take down killers" - by being trained how to use a Taser.

The Times says Britain's record level of immigration is "finally falling" after a sharp drop in the number of foreign workers and students coming to the UK. It says the number of worker visas issued in the first three months of this year was down by 45,000 compared with the same period last year - while the number of students granted entry fell by 32,000. The paper suggests the figures are the "first signs" that the government's visa crackdown is cutting the number of legal migrants.

A screening trial for prostate cancer - first announced by the government in November - is highlighted by The Mail. It says the results of what it calls the biggest trial in a generation could cut deaths from the disease by 40%. The Telegraph says the project will involve more than 300,000 men aged 45 and over, with the first phase seeing 12,500 patients invited to take part by GPs.

The demise of the British print edition of Reader's Digest is noted by The Guardian, after its editor-in-chief said financial pressures meant it was closing down with immediate effect. The paper describes the magazine as one of the biggest-selling monthly publications in the world at its peak, having a "near-ubiquitous presence in libraries and waiting rooms". But it says the UK edition's sales fell by a million copies between 2000 and 2016 as it faced the challenge of an ageing, decidedly analogue demographic of readership that "put bluntly, die off".

Photographs of the King feature in almost every paper, after he made his first major public appearance since being diagnosed with cancer by visiting a care centre for people with the disease. According to The Telegraph, "this was no ordinary engagement" but "patient and patient, discussing cancer as equals". The Express says he displayed "candour and empathy", while The Mirror says the "beaming" monarch was "a picture of rude health".
