The White House said on Thursday it was too soon to determine what caused the crash of an EgyptAir plane over the Mediterranean, it is still being investigated.
"It's too early to definitively say what may have caused this disaster," White House spokesman Josh Earnest said at a briefing. "The investigation is under way. And investigators will consider all of the potential factors that could have contributed to the crash."
The United States offered condolences to families of the victims and aid to authorities investigating the crash, it said.
Meanwhile, US Secretary of State John Kerry said earlier that he had no special information about why an EgyptAir plane disappeared on Thursday, adding that he would not speculate on the cause.
"Relevant authorities are doing everything they can to try and find out what the facts are of what happened today. I have no more knowledge than others at this point with respect to those facts," Kerry told a news conference at NATO headquarters in Brussels.
The EgyptAir Airbus A320 jet carrying 66 passengers and crew from Paris to Cairo disappeared from radar over the Mediterranean south of Greece earlier on Thursday.
