The United States began building a case Friday that would pin the blame for the downing of the passenger jet over Ukraine on separatist forces supported by Russia, in a disaster that could dramatically escalate the crisis in Ukraine.
President Barack Obama said one American was among the nearly 300 killed and called for an immediate cease-fire to allow for an unfettered investigation.
Evidence indicates that Malaysia Airlines Flight 17 was shot down by a surface-to-air missile from an area controlled by Russian-backed separatists, Obama said at the White House. He warned that the incident showed the crisis in Ukraine won't be localized or contained to the region.
"This should snap everybody's heads to attention," Obama said.
He identified the U.S. citizen who was killed as Quinn Lucas Schansman. No other details were available on the passenger, though there are news reports that he was a Dutch-U.S. citizen.
While cautioning that the exact circumstances of the crash were still being determined, Obama pointed his finger at Russia for providing support to separatists that he suggested enabled them to shoot down the plane. He said such an attack wouldn't be possible without sophisticated equipment and training – "and that is coming from Russia."
"Obviously, we're beginning to draw some conclusions given the nature of the shot that was fired," Obama said in a stern address at the White House. "There are only certain types of anti-aircraft missiles that can reach up 30,000 feet and shoot down a passenger jet."
Officials from the FBI and the National Transportation Safety Board were on their way to Ukraine to help determine what happened, Obama said. He warned that evidence must not be tampered with as a United Nations-backed investigation goes forward, and he said, "We will hold all its members, including Russia, to their word" in allowing access to the crash.
At the United Nations earlier Friday, U.S. Ambassador Samantha Power delivered an extraordinary speech rebuking Russia and noting that the U.S. could not rule out that Russian personnel had assisted separatists in firing a missile at the plane.
"Russia can end this war," Power said. "Russia must end this war."

The plane was shot down in eastern, Ukraine, near the border with Russia, in an area where Moscow's support for pro-Russian separatists has alarmed the U.S. and its European allies.
The incident occurred one day after Obama announced broader economic sanctions against Russia for its threatening moves in Ukraine.
