Following denunciations by Obama and United Nations ambassador Samantha Power over the downing of a Malaysian airliner, Pentagon Press secretary Rear Adm. John Kirby said Friday Russia is massing troops on its border with Ukraine.

Politico reports:

There are about 10,000 to 12,000 regular Russian combat troops inside their border with Ukraine, Kirby told reporters at a Pentagon briefing, an increase from a few weeks ago but a smaller force than the roughly 40,000 that were there earlier in the standoff.

Kirby also confirmed that defense officials have long observed movements of weapons and advisers from Russia to pro-Russian separatists inside Ukraine, although he said the Pentagon has not specifically seen a heavy, tracked surface-to-air missile launcher like the one believed to have shot down the Malaysia Airlines Boeing 777.
