Story highlights Two residential buildings collapse early Wednesday in Gujarat state

Authorities say seven people are confirmed dead and seven others are injured

Rescuers are searching for another 10 people who may be trapped in the rubble

At least seven people have died and 10 others are believed to be trapped after two residential buildings collapsed in western India, authorities said Wednesday.

Rescue workers are searching for survivors amid the rubble of the two three-story buildings in the Vadodara district of Gujarat state, said Vinod Rao, the top district administrator.

Seven people have been injured by the collapse, which took place around 5 a.m. Wednesday morning, Rao said.

Authorities are investigating what caused the 13-year-old buildings to come down.

In April, scores of people were killed in the collapse of an illegal multistory building in Thane, a city near the Indian financial hub Mumbai.
