A bomb detonated in an apartment in Giza’s Haram district on Thursday evening, killing at least six people and injuring at least 13 others.
The Interior Ministry said three police officers died in the explosion, one civilian was killed and two other victims have yet to be identified, according to a statement posted on its Facebook page. However, the Reuters-affiliated news site Aswat Masriya reported a death toll as high as 10, citing Mohamed Tamawy, Giza’s emergency prosecution director.
According to Tamawy, seven policemen and three civilians died in the incident.
The state-owned newspaper Al-Ahram reported the perpetrators were among the deceased, and their bodies would be examined at the morgue to help determine the type of explosives used.
The head of the Haram Police Department, Mohamed Amin, may be among the injured, an unnamed security source told the privately owned newspaper Al-Masry Al-Youm. That paper reported as many as 16 were injured in the blast, while the Interior Ministry and Aswat Masriya continue to report 13 were injured.
The explosive device allegedly went off during a police raid. The Interior Ministry said police were tipped off that Muslim Brotherhood members were hiding out in the apartment, armed with weapons and explosives.
The ministry said the apartment was set up with an improvised explosive device that was designed to detonate as soon as police forces attempted to enter. Eyewitnesses told Al-Ahram they heard a massive explosion resound through the neighborhood shortly after the police arrived at the scene.
A spate of bombings swept through Cairo in 2015, although the number of explosions has decreased in recent months.
In August 2015, the Islamic State claimed responsibility for a bombing at the National Security Agency building in Shubra al-Kheima on the outskirts of Cairo that resulted in 29 injuries.
Prosecutor General Hesham Barakat was assassinated in a car bombing in June 2015, prompting President Abdel Fattah al-Sisi to introduce the controversial new anti-terrorism law.
In February 2015, one person was killed and seven were injured in a string of explosions across Cairo and Giza.
There has also been a recent wave of attacks on tourism targets outside of Cairo. In early January, an attack on a hotel in Hurghada left two European tourists injured.
In October 2015, a Metrojet aircraft carrying mostly Russian and Ukranian tourists returning from vacation in the Red Sea resort town of Sharm el-Sheikh crashed, killing all 224 passengers and crew members aboard. The Province of Sinai (the Islamic State’s affiliate in the peninsula) claimed responsibility for the attack, saying its militants planted a bomb on the aircraft. Although Egyptian officials state that there was no evidence of terrorist activity, both Russia and the United States stated there was compelling evidence that the crash was caused by a terrorist attack.
