It said the collapse of the four-story building in the city of Damanhour was triggered by a ‘‘gas pipe explosion.’’ Search efforts are underway to find those still missing beneath the rubble. The injured were taken to a nearby hospital. No further details were immediately provided. Egyptian media reports say the two dead are children.
