Obama to speak about downed plane in Ukraine

President Barack Obama will speak about the downed plane in Ukraine from the White House this morning.

U.S. officials have said the plane was shot down Thursday by a missile. But the Obama administration has not said who it believes is responsible for firing the missile.

So far there has been no confirmation of any Americans on board the Malaysia Airlines plane that was carrying 298 people.

The plane was shot down near the border between Ukraine and Russia. The incident occurred one day after Obama announced broader economic sanctions against Russia for its threatening moves in Ukraine.
