BELGRADE, Serbia (AP) — A train has slammed into a bus in southern Serbia killing three people and injuring 22.

Serbian police say that the collision took place around 0630GMT (1:30 a.m. EST) Friday near the city of Nis. The statement says that the injured have been transferred to a nearby hospital.

Doctors say six of the injured have been seriously hurt.

The Serbian state TV says that the bus was carrying local children to school. A video from the scene shows that the bus was practically cut in half from the impact while the train partly slid off the tracks.
