Reuters reports six soldiers including four Americans were injured on Thursday in two blasts in northeast Sinai caused by improvised explosive devices, the Pentagon said. The Multinational Force and Observer peacekeepers were evacuated "by air to a medical facility where all are receiving treatment for non-life-threatening injuries," Captain Jeff Davis said in a statement. The four Americans were struck by the second blast as they were en route to help the soldiers hurt in the first, according to Major Roger Cabiness. The MFO was created as a result of the 1979 peace treaty between Egypt and Israel and is based in Sinai, the peninsula that lies between Israel, the Gaza Strip and the Suez Canal. About 650 Americans are currently assigned to the force, Cabiness said.
