Police say two boys, aged 12 and 13, stabbed at a London school are in a stable condition.
Officers are continuing to question a 13-year-old boy arrested on suspicion of attempted murder, and counter-terror police are involved.
The attack happened at Kingsbury High School in Brent, northwest London, on Tuesday.
Detective Chief Superintendent Helen Flanagan said the boys' injuries were "serious" but "thankfully not life-threatening" and they remained in hospital in a stable condition.
"Our thoughts remain with them and their loved ones at this incredibly difficult time. Specialist officers are providing their families with support," she added.
Police and ambulance crews were called at around 12.40pm on Tuesday, and the suspect, who had a weapon, was detained just after 6pm following a search.

Detective Chief Superintendent Luke Williams said on Tuesday the stabbing had not yet been declared a terror incident and police were "keeping an open mind" about the motivation behind the attack.
In a letter to parents, the school's head teacher said it was a "deeply traumatic event for the whole school community". Home Secretary Shabana Mahmood described the attack as "shocking".
