The attacks, mainly targeting police and the military, increased after the ouster of Islamist president Mohamed Morsi in 2013 by the army following protests against his rule.
Monday, September 11, the armed Islamic state militants attacked an Egyptian police convoy in the Sinai Peninsula, killing 18 police officers, reported Reuters citing sources in the security forces and medics.
Egyptian police say they killed 10 suspected militants in a shoot-out near Cairo Sunday.
The suspects had fled from northern Sinai, a hotbed of militants, to Giza, where they planned to carry out terrorist attacks in the country, the ministry said.

The police and military officials said the attack began with the detonation of roadside bombs that destroyed and set ablaze three armored vehicles and a fourth one carrying signal jamming equipment.More news: 8.1 quake rocks Mexico, deaths reported

There was no immediate claim of responsibility for the attack, which bore the hallmarks of ISIS.
One source said authorities received a tip off about the hideouts of the individuals, who they suspect of being members of Hasm, a group which has claimed several attacks around the Egyptian capital targeting judges and policemen since a year ago.
The officials spoke on condition of anonymity because they were not authorized to speak to the media. The suspected militants later opened fire with machine guns. Police said the militants had sneaked into Cairo from the volatile northern Sinai. The militants were said to be the suspected members of a splinter faction of the outlawed Muslim Brotherhood group.
Today's attack came a day after Egyptian security forces killed 10 terrorists during a raid at their hideouts in a densely populated central Cairo neighbourhood.
Nine policemen, including four officers, were injured during the two raids, it said in a statement.
