And diplomatic efforts to defuse tensions have, so far, failed to reach a conclusion.
As tensions continue to spike, here’s some key moments to watch in the ongoing Ukraine crisis.
On Saturday, Russia is set to test its strategic deterrent: its nuclear forces. The Kremlin announced Friday that Putin is “likely to be in the situation center” during military drills on Saturday, where ballistic and cruise missiles will be launched. Three decades after the end of the Cold War, both Russia and the United States have nuclear arsenals on “hair trigger” alert — that is, nuclear warheads married up to their delivery systems and ready for launch at a moment’s notice.
Kremlin spokesperson Dmitry Peskov noted that such training exercises are “quite regular,” and would involve appropriate international notifications. That’s true, up to a point: These readiness exercises are happening against the background of international tensions over Ukraine that could actualize into a major war.
Tensions escalate in Donbas
Tensions in Ukraine reached their highest in years on Friday after pro-Russian separatist leaders in the breakaway republics of Ukraine’s Donbas region called on civilians to evacuate — and after an explosion wrecked a vehicle in the separatist-controlled city of Donetsk, creating more war jitters.
Ukrainian officials deny any plans to retake Donbas by force, saying that they see this week’s incidents as an effort by Russia to create a pretext to launch an invasion. But Russian state media have already sounded the alarm, showing images of civilians departing Donbas on buses heading to Russia’s Rostov oblast, just across the border.
It is unclear how many civilians will be evacuated or if there will other incidents in Ukraine’s east that Russia might seize on as a potential pretext for war.
A diplomatic balancing act
The US and NATO make moves
The US has already bolstered its military presence in eastern Europe; the US military announced a training mission in Hungary. How will the US and its allies react to the latest moves by Russia? Will we see more evacuations of diplomats remaining in Kyiv?
