Rescuers are looking for survivors trapped under the rubble of a building in the district of el-Salam.
“The governorate crisis room was informed at 3:00 am (01:00 GMT) of the collapse of a building consisting of a basement, a ground floor and nine (upper) floors” Cairo governorate said in a statement.
Rescuers were looking for all the survivors trapped under the rubble of the building in the al-Salam district, said Khalid Abdel-Al, the administrative head of the governorate of Cairo.
At least 24 other people were injured and taken to hospitals, he said in a statement.
Police cordoned off the area, preventing bystanders and those looking for relatives in the building. Workers were seen using bulldozers to remove debris.
The cause of the building’s collapse was not immediately clear. An engineering committee has been formed to examine the structural integrity of neighboring buildings, Abdel-Al said.
Building collapses are not uncommon in Egypt, where poor-quality construction is prevalent in slums, poor city neighborhoods and rural areas.
With real estate at a high price in big cities like Cairo and the Mediterranean city of Alexandria, developers looking for bigger profits frequently violate building permits. Additional floors are often added without the proper government permit.
The government recently launched a crackdown on illegal construction across the country, jailing offenders and, in many cases, destroying buildings.
