Four people were killed and more than 20 others injured when two trains collided in Indonesia's West Java province on Friday, officials said.

Video images from broadcasters MetroTV and Kompas TV showed passengers being helped out of train carriages, some of which had gone off the rails entirely.

Ambulances gathered to take the injured to hospital, police said, following the collision at 6:03 a.m. (1103 GMT) near the provincial capital of Bandung.
