Delhi, Chennai, India (BBN)-Two buildings have collapsed in different parts of India, killing a total of at least 16 people and leaving dozens trapped.

In the capital Delhi, a four-storey building came down on Saturday, killing 10 people, including five children.

Just hours later, a 12-storey building under construction toppled in Chennai in heavy rain, leaving six people dead.

India has recently seen frequent building collapses, blamed on lax safety and substandard materials.

Rescue teams with cutters and shovels are continuing to search for survivors in the rubble in Chennai, in the southern Tamil Nadu state.

A police investigation has also been launched.

In January, at least 14 people died when a building under construction came crashing down in the western state of Goa.

At least 42 people died after a four-storey building collapsed in Mumbai last September.
