MH17 hit by missile from rebel-held Ukraine - Obama
US President Barack Obama has said a surface-to-air missile fired from a rebel-held area in east Ukraine brought down Malaysia Airlines flight MH17.
The crash on Thursday killed all 298 people on board, including 80 children.
Mr Obama called the attack "an outrage of unspeakable proportions", saying he would ensure "the truth is out".
The US and Russia clashed at the UN Security Council, with Russia's envoy putting the blame on Ukraine for its army's attacks on eastern areas.
BBC Moscow correspondent Daniel Sandford reports from the crash site in Grabova.
