U.S. Secretary of State John Kerry laid out what he called overwhelming evidence of Russian complicity in the shooting down of Malaysia Airlines flight MH17 as international horror deepened over the fate of the victims' remains.
Kerry demanded that Moscow take responsibility for actions of pro-Russian rebels in eastern Ukraine whom Washington suspects of downing the jet with a missile, and expressed disgust at their "grotesque" mishandling of the bodies.
Television images of the rebel-held crash sites, where the remains of victims had lain decomposing in fields among their personal belongings, have turned initial shock and sorrow after Thursday's disaster into anger.
Emotions ran high in the Netherlands, the home country of about two-thirds of the 298 people who died in the Boeing 777. The Dutch foreign minister has said the nation is "furious" to hear bodies were being "dragged around", while relatives and church leaders demanded they be rapidly returned home.
But the departure of dozens of corpses loaded into refrigerated railway wagons was delayed on Sunday as Ukrainian officials and rebels traded blame over why the train had not yet left the war zone, and where or when international investigators would be able to check it.
The U.N. Security Council is scheduled to vote on Monday on a resolution that would condemn the downing of the plane and demands that those responsible be held accountable and that armed groups not compromise the integrity of the crash site.
In an apparent bid to compromise with Moscow, the wording of the resolution, drafted by Australia, was changed to characterize the incident as the "downing" of the flight, instead of "shooting down," according to the final draft obtained by Reuters. Diplomats said it was unclear if Russia would support the final version.
In Washington, Kerry criticized Russian President Vladimir Putin and threatened "additional steps" against Moscow.
"Drunken separatists have been piling bodies into trucks and removing them from the site," he said on NBC television on Sunday. "What's happening is really grotesque and it is contrary to everything President Putin and Russia said they would do."
Moscow denies any involvement in the disaster and has blamed the Ukrainian military. While stopping short of direct blame on Moscow, Kerry put forward the most detailed U.S. accusations so far, based on the latest U.S. intelligence assessments.
British Foreign Secretary Philip Hammond urged Moscow to ensure international investigators had access to the crash sites. "Russia risks becoming a pariah state if it does not behave properly," he told Sky television.
Australian Prime Minister Tony Abbott said he had spoken "overnight" to Putin for the first time about the disaster, amid mounting horror over the treatment of victims' remains. At least 27 Australian passengers were on the Malaysia Airlines flight.
Abbott said an Australian investigation team was in Kiev but had been unable to travel to the site. He said there had been some improvement with the Ukrainian government offering access.
"But there's still a hell of a long way to go before anyone could be satisfied with the way that site is being treated," Abbott said. "It's more like a garden cleanup than a forensic investigation. This is completely unacceptable."
After lying for two days in the summer heat, the bodies had been removed from much of the crash site by Sunday, leaving only bloodstained military stretchers along the side of the road.
Emergency workers, who have to navigate reporting both to the authorities in Kiev and the rebels who control the crash site and other areas in the Donetsk region, will now need to pick through the debris spread across the Ukrainian steppe.
As Ukraine accused the rebels of hiding evidence relating to the loss of the airliner, a separatist leader said items thought to be the stricken jet's "black boxes" were now in rebel hands.
Investigators from the U.N. aviation agency arrived in Ukraine to help probe the crash, but a senior official said safety concerns prevented them from reaching the crash site.
"Until safe passage for them is assured, we don't send people into that kind of situation," said the official with the Montreal-based International Civil Aviation Organization.U.S. CASE
Kerry said the United States had seen supplies moving into Ukraine from Russia in the last month, including a 150-vehicle convoy of armored personnel carriers, tanks and rocket launchers given to the separatists.
It had also intercepted conversations about the transfer to separatists of the Russian radar-guided SA-11 missile system, which it blames for the Boeing 777's destruction. "It's pretty clear that this is a system that was transferred from Russia," Kerry said in an interview on CNN.
"There's enormous amount of evidence, even more evidence that I just documented, that points to the involvement of Russia in providing these systems, training the people on them," he said on CBS.
Kerry's evidence of a Russian connection tracked closely with an official unclassified U.S. intelligence summary released over the weekend. It said intelligence analysts confirmed the authenticity of an audiotaped conversation provided to the press by Ukrainian authorities of a known separatist leader boasting of downing the plane.
"We also have information indicating that Russia is providing training to separatist fighters at a facility in southwest Russia" that includes missile systems, it said.
The disaster has sharply deepened the Ukrainian crisis in which the separatists in the Russian-speaking east have been fighting government forces since protesters in Kiev forced out a pro-Moscow president and Russia annexed Crimea in March.
The United States has already imposed sanctions on individuals and businesses close to Putin but Kerry indicated that President Barack Obama might go further. "The president is prepared to take additional steps," he told Fox News, although he ruled out sending in U.S. troops.
European Union ministers should be ready to announce a fresh round of sanctions at a meeting of the EU's Foreign Affairs Council this week, said a statement from British Prime Minister David Cameron's office, issued after telephone calls with French President Francois Hollande and German Chancellor Angela Merkel.
"They ... agreed that the EU must reconsider its approach to Russia and that foreign ministers should be ready to impose further sanctions on Russia when they meet on Tuesday," it said.
The leaders also agreed to press Putin to ensure investigators had free access to the crash site.
Dutch Prime Minister Mark Rutte said all efforts were focusing on getting the train loaded with bodies to territory controlled by the Ukrainian authorities.
The European security organization, the OSCE, was negotiating with the separatists, he said, adding that a team of victim identification specialists was likely to enter the crash site on Monday.
While Ukrainian President Petro Poroshenko issued a renewed appeal for backing from the international community, some European nations, with an eye to their trade links with Russia, have been less enthusiastic about confronting Moscow.
Kerry challenged the Europeans to be more assertive. "It would help enormously if some countries in Europe that have been a little reluctant to move would now recognize this wakeup call and join the United States and President Obama in taking the lead, and also stepping up," he said.
A spokesman for Ukraine's Security Council, Andriy Lysenko, accused the rebels of a cover-up. "The terrorists are doing everything to hide the evidence of the involvement of Russian missiles in the shooting down of that airliner," he told a news conference in Kiev.
He said the rebels had taken debris and bodies from the crash site in trucks, tampering with a scene that investigators need to be secure to have a chance of determining what and who caused the plane to plunge into the steppe.
OSCE observers visited part of the crash site for a third day on Sunday. Just before their arrival, emergency workers found parts of three more bodies and put them in black body bags on the side of a road.
At the site where the cockpit fell, in a field of sunflowers near the village of Razsypnoye, residents had made a small memorial shrine of flowers, candles in tiny jars and brightly colored teddy bears.
Photocopied pictures of children and families killed in the disaster, apparently from news coverage of the victims, had been set out on the grass.
All bodies, including that of a woman who had lain naked under a tarp about 50 meters away, had been removed.
"There were five or six over here, and two or three over there," said a young man with a rifle guarding the site, who declined to give his name. "They took the bodies away to the morgue. Firstly, they were decomposing. And secondly, the smell was horrible."
