Kremlin officials say Russia ‘will not stand aside’ if Kyiv launches assault

Intelligence reports show Russian tanks and short-range ballistic missiles just 150 miles from Ukraine

Kremlin officials have said that its forces massing on the border with Ukraine could intervene if Kyiv launches an assault on Russian-backed separatists, as concerns grow about the largest military buildup since 2014.

Open source intelligence reports have shown that tanks, rocket artillery, and short-range ballistic missiles have been transported to just 150 miles from Ukraine, where Russia has established a large new military staging area.
