At least 14 people were killed when a building under construction at India’s seaside tourist resort of Goa caved in on Saturday, authorities said.

Most of the dead were construction workers, according to Goa’s police control-room officer, Sainath Kmorpant.

It was not immediately clear how many people could still be trapped in the rubble, but Kmorpant said emergency crews were still clearing the debris more than four hours after the collapse was reported.

The five-story building came down at around 3:15 p.m., according to police.

The cause of the collapse is not yet known.
