Six international peacekeepers stationed in Egypt, including four American soldiers, were wounded by two improvised explosive devices on Thursday, according to the Defense Department. The peacekeepers were part of the Multinational Force and Observers, a mission stationed in Egypt’s restive Sinai Peninsula to support the 1979 peace treaty between Egypt and Israel. The six wounded soldiers were airlifted to a medical facility where they were being treated for injuries that were not life-threatening. “The safety and security of U.S. forces remains our top priority, and we are committed to taking necessary steps for their protection,” said Jeff Davis, a Navy captain who is the director of press operations for the Defense Department, which provided no further information on the soldiers’ injuries or what had happened.
