At least twenty-five people were killed in northern India when a disused railway shed caved in on them as it was being demolished.

The accident took place at Tundla, an important railway junction near the city of Agra, during work to upgrade the station.

The locomotive shed, which was built during British rule, was being removed to make way for the widening of platforms when it suddenly collapsed after a pillar supporting the roof was struck by a bulldozer.

Railway workers, labourers and on-lookers were trapped in the debris and a crane had to be brought in to help the rescue efforts.

Eleven people were injured and police say more victims could be found beneath the rubble. An investigation has been launched into how so many people came to be standing inside the shed as demolition got underway.
