6 peacekeepers, including 4 US soldiers, injured in Sinai explosions, Pentagon announces

The Defense Department announced late Thursday that four U.S. soldiers and two Multinational Force and Observers' peacekeepers were injured by improvised explosive devices in the northeast Sinai region of Egypt.

The Pentagon said the injured soldiers were airlifted to a medical facility, where they were being treated for non-life-threatening injuries. The department did not identify the wounded personnel.

Capt. Jeff Davis, Director of Press Operations, said in a statement "the safety and security of U.S. forces remains our top priority and we are committed to taking necessary steps for their protection." 

The mission of the Multinational Force and Observers is to support the 1979 peace treaty between Israel and Egypt.
