NEW DELHI (AP) — Police say a dilapidated building has collapsed in the Indian capital, killing at least two people and rescuers were searching for four others who are trapped.

Police officer Madhur Verma says nine people have been pulled out so far after the four-story building Saturday. More than a dozen residents were trapped initially in the collapse of the 50-year-old structure.

The Press Trust of India news agency said the building collapse was triggered by construction work on an adjacent plot of land.

Building collapses are common in India, where high demand for housing and lax regulations have encouraged some builders to cut corners, use substandard materials or add unauthorized extra floors.
