Vice President Joe Biden said on Thursday that the downing of a Malaysian airliner near the Ukraine-Russia border apparently was "not an accident" and that the passenger jet was "blown out of the sky."
Biden, in a speech in Detroit, said there may have been Americans on board and determining that was the first priority for the United States.
He called the downing of the plane a "grave situation" and said there are many questions that need to be answered.
