The Army of Islam was founded in late 2005. The Army of Islam split from Hamas due to the members agreeing with Al-Qaeda's ideology which goes against Hamas'. The Army of Islam never fully gained the support of Al-Qaeda nor did it get any praise during its early years in activities, though the Army of Islam became allies with
Tawhid al-Jihad and, later,
Ansar Bait al-Maqdis which led to the organization pledging
bay'ah to the
Islamic State and its leader at the time,
Abu Bakr al-Baghdadi. An Israeli helicopter strike killed Army of Islam senior leader Mohammed Jamil al-Nemnem, 27, in Gaza City on 3 November 2010. Nemnem was second-in-command to Mumtaz Doghmush. Egypt had reportedly tipped-off Israel that Nemnem was helping plan an attack on the
Multinational Force and Observers in the
Sinai Peninsula. In a subsequent statement, Israel claimed Nemnem was involved in directing multiple terrorist attacks targeting Israelis in recent years. The strike was coordinated with Israeli
Shin Bet and occurred around dawn on a busy street in Gaza City, and cited the same security issues as that in the killing of Namnam. In 2015, the group had reportedly pledged allegiance to the Islamic State and joined as a part of the
Islamic State – Sinai Province. By 2018, the group faced increasing repression by Hamas which was unwilling to tolerate its extremist activities. In turn, the group considers Hamas an
apostate organization, and has called upon Muslims to carry out
lone wolf attacks against Israel. ==Ideology==
