Dhaka, July 25 -- A roof collapse at a school in India's western state of Rajasthan on Friday claimed the lives of at least four children and left 17 others injured, according to local media reports. Many students are still believed to be trapped beneath the debris.

A local police official, speaking to Reuters on condition of anonymity, said the building was old and the collapse may have been triggered by heavy rainfall in the area.

Rajasthan Education Minister Madan Dilawar told AajTak news channel that the roof collapsed following morning prayers while 25 to 30 students were present in the room.

News channel footage showed local residents at the scene, while anguished family members wept as authorities used cranes to clear the rubble...
