Russia's failure to cease support for separatists in Ukraine has contributed to the Malaysian airliner tragedy, a No 10 spokeswoman has said. The spokeswoman added that Mr Cameron had made clear to Mr Putin that the shooting down of MH17 was "totally unacceptable".
The evidence suggested that pro-Russian separatists were responsible and the Prime Minister made clear that if Russia wants to put the blame elsewhere they would need to present compelling and credible evidence.
The delay and restrictions so far were completely unacceptable and indefensible.
Thousands of online users have taken to social media to call for the victims of the Malaysian airliner crash to be returned to loved ones.
United States intelligence officials admitted that they do not know who fired the surface-to-air missile that downed flight MH17.
