Amid allegations from Ukraine that Russia has been massing troops at their shared border, Russian Foreign Minister Sergei Lavrov has warned that any attempts at a "new war" in eastern Ukraine would end up destroying that country.

The threat lands as Moscow and Kyiv trade blame over a recent spike in violence in the years-long conflict between Ukrainian government forces and Russia-backed terrorists. 

Kyiv claims the terrorists are "systematically violating a cease-fire” agreed in July and blames Russia for a purported build-up of Russian military forces near their shared border- an accusation rejected by the Kremlin.
