BANGKOK: Two trams used to shuttle visitors around a zoo in northeastern Thailand collided Sunday, killing five people and injuring more than 30, police said.

The accident at the Kao Suan Kwang Zoo in Khon Kaen province occurred when one tram driver lost control due to a problem with the vehicle's brakes and slammed into a tram in front, said police Col. Pichit Deeya.

The impact caused both trams to overturn, crushing a passenger who died at the scene, Pichit said. Four other people died from injuries at a local hospital, he said, adding that all the victims were Thai nationals.

Among the dead was a 2-year-old girl. About 10 other children were injured, ranging in age from 3-12, Pichit said.
