Two people were killed and four others injured in the collapse of two buildings in north Cairo's Rod El-Farg district on Tuesday, Al-Ahram Arabic website reported.
According to Al-Ahram, the buildings collapsed on Monday as the result of the collapse of another five-story building nearby.
The civil-security forces managed to rescue four injured people from the ruins of the two buildings.
However, two other people, a 45-year-old-woman and a five-year-girl, died in the collapse.
Rescue workers are still conducting search-and-rescue efforts in the hope of finding more survivors.
The Rod El-Farag district, once known for its fruit-and-vegetable market, is a crowded area with poor-quality housing.
