The number of killed people after an eleven-story building collapsed in Egypt's port city of Alexandria rose to 19, the country's Health Ministry officials said on Monday.

Rescuers have recovered 19 bodies from the debris in the Gomrok area. The top building suddenly collapsed on Saturday, crushing down three other nearby residential buildings.

Nine injured residents have been rescued. Efforts to search more survivors are still underway.

In Egypt, collapses of buildings occur often due to violations of construction rules, poor quality or maintenance.
