The UK has elevated its official terror threat level from substantial to severe, signaling that an attack is considered likely within the next six months. The move follows a series of antisemitic incidents, including the recent stabbing of two Jewish men in north London; the suspect was charged with attempted murder earlier today. In response, the government has labeled antisemitism an emergency and pledged increased security for Jewish communities. Meanwhile, Prime Minister Keir Starmer faced heckling on Thursday during a visit to the area where the attack occurred, as Peter O’Brien reports.
