Following an uptick in violence between government forces and rebels in the breakaway region, Russia’s foreign minister accused Ukrainian leaders of attempting to pull Moscow into the crisis in eastern Ukraine.

“We see attempts to carry out provocations, draw a response from the militia, and lure Russia into some kind of combat action,” Russian Foreign Minister Sergei Lavrov said on state television.

After government forces used a Turkish-made Bayraktar TB2 drone to target a position controlled by Russian-backed separatists last week, Russia accused Ukraine of worsening the situation.

Rebels supported by Moscow have been fighting government troops in Ukraine’s Donbass region since 2014, soon after Russia seized and annexed the Crimea peninsula from Ukraine. Kyiv says at least 14,000 people have been killed.
