Rescuers assess whether further workers are trapped under the rubble
At least five people have died and 15 have been injured after a partially constructed bridge collapsed in Delhi, Indian officials say.
A pillar supporting part of the structure collapsed, a spokesman for the Delhi Rail Corporation said.
The men who died were reported to be labourers working on the bridge, part of the city's new metro system.
The accident happened in the early hours of Sunday morning. Rescue crews are checking others are not trapped.
A labourer working on the site said that at least 25 men were working there when a concrete supporting pillar collapsed, Reuters reports.

"Sacks of cement were being taken up. Two to three were taken up and then suddenly the bridge collapsed," Mukesh said.
A police spokesman said the accident happened as workers lifted heavy concrete slabs for the bridge.
One slab slipped, crushing the metal beams of the bridge beneath and rupturing a water pipe.
It is the second accident involving metro construction projects in less than a year.
In October, two people were crushed to death and 12 injured when another bridge under construction collapsed on to a bus and cars below.
