NEW DELHI - At least three persons were killed and several others injured when parts of an under-construction bridge collapsed near the Mumbai airport late Wednesday night, a senior police official said Thursday.

"The bridge collapsed suddenly at 10.30 pm when several construction workers were working at the site. They were all trapped under the debris and were rescued by fire tenders. While one died on the spot, three others succumbed to their injuries at the hospital where they were admitted," he said, on condition of anonymity.

Local TV channels beamed footage of rescuers pulling out those trapped under the debris at the under-construction bridge which, when completed, will connect international and domestic terminals of the Mumbai airport.

The police have booked the private contractor of the site for negligence, the official added.
