Terrorist attacks in Egypt – which spiked in the wake of the 2013 ouster of the Muslim Brotherhood President Mohamed Morsi, most notably in North Sinai – have declined in recent years following massive and successive security and military operations.
The attacks targeted security forces, particularly at military and police checkpoints, as well as civilians, causing hundreds of casualties.
Hundreds of terrorists were killed in anti-terror military operations, according to Armed Forces periodical reports.
In 2018, the Armed Forces launched a major counterterrorism drive, Comprehensive Operation Sinai 2018, that has succeeded in the near eradication of terrorism from North Sinai as well as the Nile Delta and desert areas.
