A four-story apartment building in northern Egypt collapsed on Friday, killing at least two people and injuring 20 others, authorities said.

The building's collapse in the Nile Delta city of Damanhour was preceded by a "gas pipe explosion," according to a brief government statement.

Search efforts were underway to find those still missing beneath the rubble while the injured were transported to a nearby hospital, it said. No further details were immediately provided.

Last month, six people were killed in an apartment block collapse in the southern city of Asyuit.
