Pressure is mounting on Russia and Ukraine to give some answers to what caused the crash of a Malaysia Airlines passenger plane carrying 298 people, which U.S. intelligence officials said was caused by a surface-to-air missile.
Amid increasing international calls for an investigation into what brought down flight MH17 over the troubled region of eastern Ukraine, Thursday, U.S. Vice President Joe Biden said the plane crash was "not an accident," adding that it was "blown out of the sky."
Officials on both sides of the crisis in Ukraine have so far blamed each other for the plane crash, with authorities in Kiev releasing what is claimed to be a recording of a Russia-backed rebel admitting to firing the missile that downed the MAS aircraft while Russian President Vladimir Putin said Ukraine must take responsibility for the disaster.
So far, emergency services on the site of the crash in the Donetsk region of Ukaine have uncovered 181 bodies.
In a packed press conference in Kuala Lumpur Friday, Malaysian Transport Minister Liow Tiong Lai said it would be "an outrage against human decency" if the airliner was found to have been shot down.
There were reports Friday that the crashed plane's flight recorders (the so-called black boxes) had been located. Reuters reported that Russian foreign minister Sergey Lavrov saying that Moscow did not plan to take the recorders from pro-Russian separatists in eastern Ukraine, further complicating efforts to find out what happened to flight MH17.
Hillary Clinton, former U.S. secretary of state, told the "Charlie Rose Show" that the "there does seem to be some growing awareness that it probably had to be Russian insurgents."
Clinton added that if there was evidence linking Russia, Europe would have to strengthen considerably their sanctions against Moscow.
Meanwhile in Berlin, German Chancellor Angela Merkel told reporters that Russia must work towards a political solution in Ukraine, and that those responsible for the Malaysian plane being downed must be brought to justice.
Her call to action was joined by U.K. Prime Minister David Cameron who said the "absolutely shocking incident" should not "be allowed to stand."
