Leaders of the nations which lost citizens on the flight have expressed their anger at Russia's response to the disaster.

Australian prime minister Tony Abbott told ABC a short time ago that “Russia can’t wash its hands of this.”

"My fear is that Russia will say the right thing but still try to interfere on the ground," he said.

He wouldn’t be drawn on whether he had sought to make contact with Putin, but said the most senior person he has access to at this time is the Russian trade minister, here for the G20, but he was left “in no uncertain terms our concerns and demands” for a full investigation.

Abbott also offered to call any families of the victims who would like to speak to him or foreign minister Julie Bishop, but said he did not want to intrude if they did not want to speak.

Earlier, UK prime minister David Cameron said: "this is a direct result of Russia destabilising a sovereign state, violating its territorial integrity, backing thuggish militias, and training and arming them. We must turn this moment of outrage into a moment of action."

Dutch prime minister Mark Rutte said Putin has "one last chance to show he means to help."

"I was shocked at the pictures of utterly disrespectful behaviour at this tragic spot. It's revolting."

Malaysian transport minister Datuk Seri Liow Tiong Lai said the integrity of the crash site had been compromised.

“Interfering with the scene of the crash risks undermining the investigation itself. Any action that prevents us from learning the truth about what happened to MH17 cannot be tolerated,” Liow said.

“Failure to stop such interference would be a betrayal of the lives that were lost."
