Building collapse in New Delhi kills 64

Rescuers hammered slabs of concrete and dug with their hands Tuesday to pull survivors and bodies from a four-story apartment building that collapsed into a mountain of rubble in a poor New Delhi neighborhood. At least 64 people were killed and scores injured, Associated Press said.

The 15-year-old building housing about 200 people — mostly migrant workers and their families — collapsed Monday evening in New Delhi's congested Lalita Park area, where emergency efforts were hampered because vehicles had difficulty navigating its narrow alleyways.

The cause of the collapse was not immediately clear. One official said the building may have been weakened by water damage following monsoon rains; Residents said the landlord was illegally constructing an additional floor on the building.

Officials ordered the evacuation of at least one other nearby building that they feared could collapse too.
