A still photo from a video posted by Alexandria Governorate Facebook page for the building that collapsed on Monday.
According to Governor of Alexandria Mohammed El-Sherif, rescue teams are searching for any victims who may be trapped under the rubble.
The body of one victim has been recovered as of Monday evening, according to a statement by the Ministry of health.
Two more people were rescued alive from the building itself.
Four passersby were injured, according to Undersecretary of the Ministry of Health and Population Amira Tahio in a phone interview earlier in the day with the Al-Hadath satellite channel.
Their injuries are mild to moderate, ranging from a broken leg to mild asphyxiation to scratches and bruises, stated Tahio.
All the injured left the hospitals by Monday night after receiving medical treatment, according to the ministry.
Ambulances remain at the scene in anticipation of any other injuries or deaths.
Authorities are still searching for victims, and the total number of casualties is unknown. It is unclear how many people were inside the building as it is a vacation property with no regular tenants.
The collapse crushed parked cars and shops below the building.
It also ignited a fire that was subsequently extinguished
The property, dating back to the 1970s, had been previously condemned.
"The top floor of the building had a demolition order, and the entire property was examined by the committee responsible for inspecting buildings at risk of collapse," the governor said.
Prosecutor-General Hamada El-Sawy has ordered an investigation into the collapse, according to a statement from the Public Prosecution.
A team from the prosecution inspected the scene and instructed civil defence and municipal officials to secure the area and adjacent properties as necessary.
They also formed a committee from the governorate's Housing Directorate to determine the cause of the incident and examine the building's file, according to the statement.
The Decent Life Foundation will provide financial compensation of EGP 25,000 to each victim’s family, according to a Monday announcement.
The foundation's field monitoring teams in Alexandria have been deployed to provide on-ground support to the victims, the announcement added.
