Obama mourns victims, calls for action
The President just said at least one American was among those killed when MH17 was shot down.
"Their deaths are an outrage of unspeakable proportions," he said.
And there seems little doubt as to what happened now.
"The plane was shot down," Obama said.
"There has to be a credible international investigation" into what happened.
Obama also honored the "nearly 100" scientists, researchers and health workers killed on MH17 who had been heading to Australia for an AIDS conference.
Back on what led to the attack and the unrest in eastern Ukraine, Obama says: "Russia, these separatists, and Ukraine, all have the capacity to put an end to the fighting. Meanwhile, the United States is going to continue to lead efforts within the world community to de-escalate the situation, to stand up for the sovereignty and territorial integrity of Ukraine and to support the people of Ukraine as the courageously work to strengthen their democracy and their own decisions about how to move forward."
Obama is echoing and adding to the U.S. criticism of Russia voiced earlier today by U.N. Ambassador Samantha Power.
'We have increasing confidence that it (the missile) came from areas controlled by separatists," he said.
"A group of separatists cannot shoot down.. fighter jets without sophisticated equipment.. And that is coming from Russia," Obama added, referring to the downing of some military planes before yesterday's attack on MH17.
"This will be a wake up call for Europe and the world that there are consequences for escalating conflict in eastern Ukraine," the President said.
