The Sinai insurgency was an insurgency campaign in the Sinai Peninsula of Egypt launched by Islamist militants against Egyptian security forces, which also included attacks on civilians. The insurgency began during the Egyptian Crisis, during which the longtime Egyptian president Hosni Mubarak was overthrown in the 2011 Egyptian revolution.
The campaign initially consisted of militants, mainly local Bedouin tribesmen, who exploited the chaotic situation in Egypt to launch a series of attacks on government forces in Sinai.
