In recent years, Egyptian troops have been engaged in efforts to quell rampant militancy across the Sinai Peninsula.

The battle has led to the deaths of hundreds of troops and militants, including those with the Takfiri Velayat Sinai group.

In October 2014, a state of emergency was declared across the whole peninsula following a deadly terrorist attack that claimed the lives of 33 soldiers.

Previously known as Ansar Bait al-Maqdis, the outfit has pledged allegiance to the ISIS terror group, which is mainly active in Iraq and Syria.

The militants also claimed responsibility for shooting down a Russian plane in a mountainous area of Sinai Peninsula in late October last year.
