A huge fire at a police complex in Egypt has injured at least 38 people, according to emergency services and local media.
Videos posted on social media show the building covered in flames.
An investigation into the cause of the fire has been ordered, according to the AFP news agency.
Civil defense sources said that the fire caused parts of the headquarters of the Directorate of Security to collapse.
Egypt’s health ministry has sent 50 ambulances and two military aircraft to the building, with at least 24 people being treated for asphyxiation with another two treated for burns.
There are fears that the number of people injured could be higher with one Egyptian journalist reporting that because of the size of the fire, there could be deaths.
Two witnesses who spoke to the Reuters news agency said that firefighters initially struggled to get the fire under control, but local media says that after more than three hours they did manage to contain it.
Deadly fires are not uncommon in Egypt due to fire codes rarely being enforced and slow emergency response times. In August last year, a fire caused by a short circuit killed 41 people in a church in Cairo.
