Obama has confirmed that one American was killed on a passenger plane shot down over Ukraine.
While addressing reporters at the White House Friday, Obama said the airliner was shot down by a surface-to-air missile in an area controlled by Russian-backed separatists.
The president called it a global tragedy in remarks from the White House, one day after Malaysia Airline Flight 17 crashed.
Obama called for an immediate cease fire in Ukraine, and a credible international investigation. "Eyes of the world on eastern Ukraine," Pres. Obama said. "We're going to make sure that truth gets out."
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.
