JERUSALEM — A helicopter carrying members of a multinational peacekeeping force crashed on Thursday near Sharm el Sheikh in the Sinai Peninsula of Egypt, killing six Americans, a French citizen and a Czech citizen.
The peacekeeping force, Multinational Force and Observers, said that nine of its members were involved in the crash and that eight had died. One person survived and was medically evacuated, the force said in a statement.
“At this point, there is no information to indicate the crash was anything except an accident,” the statement said.
The force, known as the M.F.O., supervises the implementation of the 1979 peace treaty between Egypt and Israel. It consists of 1,154 troops from 13 countries, including Australia, Britain, Fiji, the United States and Uruguay.
The force was born in 1981 out of the inability of the Security Council to obtain approval for the placement of the United Nations peacekeeping force in Sinai — pushing Israel and Egypt to negotiate the agreement that established the M.F.O.
The M.F.O. operates out of two military bases in Egypt: a South Camp near Sharm el Sheikh, which acts as the headquarters as well as an operational and logistical base. A North Camp is in the town of El Gorah in northern Sinai, near the Egyptian-Israeli border.
Over the past few years, terrorism has spread in the Sinai Peninsula, with militants affiliated with the Islamic State attacking security officers and even downing a Russian passenger jet. The M.F.O. peacekeepers have not been spared, with two blasts injuring six soldiers, including four Americans, in 2015.
Pentagon officials declined to identify the American service members killed in the crash, pending notification of family members. Among the U.S. military assigned to the peacekeeping force are more than 450 members of the Texas National Guard deployed to Sinai earlier this year.
Acting Defense Secretary Christopher C. Miller expressed his condolences in a Twitter message on Thursday: “We are saddened by the loss of 6 US and 2 partner nation service members in a helicopter crash in the Sinai Peninsula operating with the Multinational Force and Observers (MFO).”
The Israeli military said one of its helicopters carrying elite search and rescue soldiers from Air Force Unit 669 had evacuated an injured American peacekeeper to an Israeli hospital for medical treatment. The Soroka Medical Center in Beersheba, Israel, said an American wounded in the crash was admitted to its trauma unit in moderate to serious condition.
Israel’s ministers of defense and foreign affairs sent their condolences to the families of those killed and wished a speedy recovery to the wounded. Both praised the importance and contribution of the force.
“These troops were part of a peacekeeping force bravely protecting the stability and security of the region,” Benny Gantz, the defense minister, said in a statement.
