WASHINGTON (QHA) -

Eyes of the world are on eastern Ukraine. We're going to make sure that truth gets out.

U.S. President Barack Obama said, concerning the Malaysia Airline plane crash that killed almost 300 on the board.

Speaking in Washington, Obama noted that evidence indicated that a Malaysian airliner was shot down by a surface-to-air missile launched from an area controlled by Russian-backed separatists in Ukraine.

He he also said the separatists have received a steady flow of arms from Russia, including antiaircraft weapons.

Obama said Ukraine, Russia, and pro-Russian separatists must adhere to an immediate ceasefire and not interfere with an international investigation into causes of the downing of Malaysia Airlines Flight MH17.

The U.S. President said that time and time again Russia has refused to take concrete steps necessary to de-escalate the crisis in eastern Ukraine, and that Russia has continued to violate Ukrainian sovereignty and to support violent separatists.
