Ansar Bait al-Maqdis
The Islamic State of Iraq and the Levant linked militant group Wilayat Sinai, formerly known as Ansar Bait al-Maqdis until it pledged allegiance to ISIL in November 2014, claimed responsibility for the attacks on an affiliated Twitter account. Wilayat Sinai said that the incidents were part of a series of attacks that they had dubbed "We Swear We Will Revenge", which the group dedicated to "avenge for women and girls" held in government prisons.
