“Where we once had relatively benign missions conducting peace support operations, such as the MFO mission, [it is] now turning more hostile … Toxic environments where, in the case of the Sinai, [ISIS] in the Sinai is now grown in strength and impedes the conduct of the mission,” Chief of the Defence Staff of the Canadian Armed Forces Jonathan Vance told CBC News. A peacekeeping expert says the mandate of the MFO mission in Sinai “has not kept up with the changing circumstances on the ground and the threats.” CBC news notes that the MFO has had to deal with an increase in violence from Wilayat Sinai, which has launched rocket and mortar attacks against at least one of the MFO’s two bases in the Sinai.
