Counter-terrorism officers are leading the investigation into the stabbing of two boys, aged 12 and 13, at a school in north-west London. Police arrested a 13-year-old boy on suspicion of attempted murder and found a weapon at the scene that they believe was used in the attack. Both injured boys are currently in serious condition.

Detectives are not looking for any other suspects at this time, and although specialists are leading the case, they have not declared the incident a terrorist act. The school's headteacher confirmed the stabbings took place and announced that the lower school will stay closed for now. Several local officials have expressed their shock and offered support to those affected.
