Reports suggest there were many school children on the buses

Japanese police have arrested a man after a knife attack outside a train station that left at least 13 people injured.

The man boarded two buses and attacked passengers - who were predominantly school children - in the city of Toride, some 40km (25 miles) north-east of Tokyo, reports say.

Four people were stabbed, and others were injured as they fled, police say.

A 27-year-old man has been arrested on suspicion of attempted murder.

One of the victims would need to remain in hospital for several weeks, while the others were not seriously injured, said a spokesman for the local fire department.

Correspondents say the attack has brought back memories of an incident in central Tokyo in 2008, in which a man armed with a knife killed seven people.
