Why Luhansk and Donetsk are key to understanding the latest escalation in Ukraine

In the latest flare-up of the crisis in Ukraine, Russian President Vladimir Putin on Monday recognized the independence of two breakaway regions in Ukraine’s east as independent and ordered military forces to deploy there.

The rebel-controlled territories, Luhansk and Donetsk, comprise a larger region called Donbas that borders Russia. The two territories have been led by pro-Russia separatists for nearly a decade.

Experts warn that Putin’s order for troops to carry out what he called “peacekeeping functions” in the region — and what President Biden has now called the start of an invasion — could lay the groundwork and provide the pretext for a larger Russian military incursion into Ukraine.
