News reports say an attacker with a knife who tried to hijack a bus in southeastern China killed five people and wounded 21.

The Beijing News newspaper said on its website the attack occurred Tuesday afternoon aboard a public bus in Longyan in the coastal province of Fujian, south of Shanghai.

The newspaper and other reports gave no details of the attacker's identity or motive.

A brief video clip on the Beijing News website showed a half dozen police officers wrestling the attacker to the ground in the middle of a street as traffic flowed past.
