At least one American was among the almost 300 killed, he said, a revelation that raises the stakes in a pivotal incident in deteriorating relations between Russia and the West.
Calling it “an outrage of unspeakable proportions”, Obama stopped short of directly blaming Russia for the incident but warned that he was prepared to tighten economic sanctions. He echoed international calls for a rapid and credible investigation and ruling out U.S. military intervention.
But, noting the global impact of the crash, with victims from 11 countries across four continents, he said the stakes were high for Europe, a clear call for it to follow the more robust sanctions on Russia already imposed by Washington.
Russia, whom Obama said was letting the rebels bring in weapons, has expressed anger at implications it was to blame, saying people should not prejudge the outcome of the inquiry.
There were no survivors from the Malaysia Airlines flight MH17 from Amsterdam to Kuala Lumpur, a Boeing 777. The United Nations said 80 of the 298 aboard were children. The deadliest attack on a commercial airliner, it scattered bodies over miles of rebel-held territory near the border with Russia.
Makeshift white flags marked where bodies lay in corn fields and among the debris. Others, stripped bare by the force of the crash, had been covered by polythene sheeting weighed down by stones, one marked with a flower in remembrance.
One pensioner told how a woman smashed though her roof: “There was a howling noise and everything started to rattle. Then objects started falling out of the sky,” said Irina Tipunova, 65. “And then I heard a roar and she landed in the kitchen.”
An American-Dutch dual national was confirmed aboard – more than half those who died were Dutch – and U.S. investigators prepared to head to Ukraine to assist in the investigation.
Staff from Europe’s OSCE security body visited the site but complained that they did not have the full access they wanted.
The scale of the disaster could prove a turning point for international pressure to resolve the crisis in Ukraine, which has killed hundreds since pro-Western protests toppled the Moscow-backed president in Kiev in February and Russia annexed the Crimea peninsula a month later.
“This outrageous event underscores that it is time for peace and security to be restored in Ukraine,” Obama said, adding that Russia had failed to use its influence to curb rebel violence.
While the West has imposed sanctions on Russia over Ukraine, the United States has been more aggressive than the European Union. Analysts say the response of Germany and other EU powers to the incident – possibly imposing more sanctions – could be crucial in deciding the next phase of the standoff with Moscow.
Some commentators even recalled Germany’s sinking of the Atlantic liner Lusitania in 1915, which helped push the United States into World War One, but outrage in the West at Thursday’s carnage is not seen as leading to military intervention.
The U.N. Security Council called for a “full, thorough and independent international investigation” into the downing of the plane and “appropriate accountability” for those responsible.
German Chancellor Angela Merkel said it was too early to decide on further sanctions before it was known exactly what had happened to the plane. Britain said the facts must be established by a UN-led investigation before additional sanctions were seriously considered.
Kiev and Moscow immediately blamed each other for the disaster, triggering a new phase in their propaganda war.
Ukraine has closed air space over the east of the country as Malaysia Airlines defended its use of a route that some other carriers had been avoiding.
More than half of the dead passengers, 189 people, were Dutch. Twenty-nine were Malaysian, 27 Australian, 12 Indonesian, nine British, four German, four Belgian, three Filipino, one America, one Canadian, one New Zealand. Several were unidentified and some may have had dual citizenship. The 15 crew were Malaysian.
A number of those on board were travelling to an international AIDS conference in Melbourne, including Joep Lange, an influential Dutch expert.
“We lost somebody who wanted to make the world a better place,” said his friend Marcel Duyvestijn.
