Foreign Ministry sources following the plane crash in Buffalo, New York, which left 50 people dead, expressed concerns on Friday for the lives of two Israeli citizens who may have been onboard the aircraft.

The concerns arose after two families contacted the ministry after being unable to contact their loved ones.

The Israeli Consulate in New York is also involved in an effort to inquire for more details on the victims of the crash.

A Continental Airlines spokesperson said, "At this point, we have no knowledge of any Israelis onboard the plane." However the Foreign Ministry stated that the airline had contacted the two Israelis' families.

Continental Connection Flight 3407 flying from Newark Liberty International Airport in New Jersey headed for Buffalo Niagara International Airport crashed into a house while coming in to land Thursday night.

The crash sparked a fiery explosion that killed all 49 people on board and one person on the ground.

The Foreign Ministry continued efforts to gather information on the two Israelis suspected to have been on the flight and the Israeli Consulate in New York is in constant contact with the families.
