Ansar Bait al-Maqdis

Ansar Bait al-Maqdis (ABM, أنصار بيت المقدس Anṣār Bayt al-Maqdis, "Supporters of the Holy House"), also known as Ansar Jerusalem ("Supporters of Jerusalem") is an active militant group that has been operating in the Sinai Peninsula since the Egyptian Revolution of 2011, with its operations increasing in the wake of the overthrow of Mohammed Morsi in July 2013.

The group is believed to be the main group behind the militant activity in the Sinai. The group recruits Bedouins as well as other Egyptians and people of other nationalities. Nabil Na'eem, a former member of Egyptian Islamic Jihad, has claimed that the group is funded by the Muslim Brotherhood's deputy chairman Khairat al-Shater. Ten leaders from the group were reported to have escaped from the Sinai to Gaza and Marsa Matrouh in late 2013. It was designated as a terrorist organization by the US State Department on 9 April 2014, as well as by the government of the United Kingdom on 7 April 2014.
