Two children were injured and hospitalised after accidentally triggering two Improvised Explosive Devices (IEDs) Monday night.
A group of children had been playing on the rooftop of a building in the Giza neighbuorhood of Imbaba when they set off the explosive devices, a statement by the Ministry of Interior said. A third IED which contained a large amount of gunpowder and nails was deactivated.
Security forces are carrying out intensive efforts to stand on the details of the incident, the ministry said.
IED explosions have become increasingly recurrent and attacks frequently target security forces. Cairo has witnessed several explosions since January, after Sinai bore the majority of the bombings and attacks in the country since July.
Earlier this week, a homemade explosive thrown from a motorcycle wounded at least four people at a political rally. Last month, a bomb attack in Lebanon Square, Giza killed a police officer, after suspects dropped the bomb from an overpass and immediately fled the scene. On 16 April, two separate bombings in two Giza neighbourhoods, Dokki and Feisal, left five people injured.
In January, Greater Cairo was hit by four blasts in one day, the deadliest of which targeted the Cairo Security Directorate in Downtown Cairo, leaving four people dead and dozens injured. Another two died on that day from the other blasts.
Militant groups Ansar Beit Al-Maqdis and Agnad Misr have carried out a number of attacks on security outposts and have claimed responsibility for attacks in Giza, Cairo, Ismailia and Sinai.
Last September, Interior Minister Mohamed Ibrahim was the target of an assassination attempt that was later claimed by the recently designated terrorist organisation Ansar Beit Al-Maqdis.
Agnad Misr claimed responsibility for the series of explosions that occurred outside Cairo University on 2 April, which killed Director of Western Giza Investigation Tarek El-Mergawy and injured five other officers.
