[Ed. – This is certainly (a) possible and (b) likely. As the Breitbart report indicates, ISIS has had a presence in the Sinai for some time. Israel and Egypt have been making accommodations to each other regarding force deployments in the Sinai since the start of the Arab Spring, given the unstable security situation there.]
A news agency known for its close ties to the Islamic State claimed that Israeli aircraft on Tuesday struck outposts of Wilayat Sinai, the IS’s branch in the Egyptian Sinai.
With no documentary evidence to back up its claim, the Amaq News Agency reported that seven “Israeli drones, war-planes and helicopters” bombed targets in the IS-heavy north-eastern Sinai.
Contacted by Breitbart Jerusalem, a spokesperson for the Israel Defense Forces declined to comment, explaining it is the IDF’s general policy to refrain from commenting on reports of operations outside the boundaries of Israel and the Gaza Strip.
IS has kept mum on the alleged incident, the agency added, and the number of casualties remains unclear.
