Mounting evidence Russia provided weapon used to shoot down MH17

John Kerry (United States Secretary of State.)

Secretary of State John Kerry hit the political talk show circuit on Sunday, saying there is mounting evidence that Russia was involved in providing the weapon separatists are accused of using to shoot down Malaysia Airlines Flight MH17.
On NBC's "Meet the Press," Kerry said “there's a buildup of extraordinary circumstantial evidence” Russia provided the weapon used to shoot down the plane.
Kerry said the United States tracked imagery of the launch of a surface-to-air missile around the time the aircraft disappeared from radar.

"We know that [separatists] had an SA-11 system in the vicinity, literally hours before the shoot-down took place," he continued. "We have the intercepts of their conversations, talking about the transfer and movement and repositioning of the SA-11 system. The social media showed them with this system moving through the very area where we believe the shoot-down took place, hours before it took place."
Kerry called on Russian President Vladimir Putin to call out the separatists and encourage them to take part in a political reconciliation process with the Ukrainian government.

"This is a moment of truth for Mr. Putin and for Russia," Kerry said. "Russia needs to step up and prove its bona fides if there are any left."
Kerry also condemned the rebels' response to the crash, calling it "grotesque."

“Drunken separatists are stacking bodies into the back of trucks, removing materials from the site,” Kerry told Stephanopoulos. “This is an insult to everybody. It’s really a moment of truth for Russia to step up and be part of the solution, not part of the problem.”
We are not drawing the final conclusion here," Kerry said on "Meet the Press." "But there is a lot that points at the need for Russia to be responsible."
