At the Munich Security Conference, a truce between Russian-backed separatists and the Ukrainian army, per the Minsk Protocol, takes effect Monday. Pending a permanent political agreement, Russian President Vladimir Putin orders that civil registration documents issued in separatist-held areas of Donetsk and Luhansk in eastern Ukraine be temporarily recognized. Ukrainian authorities say this violates provisions in the Minsk agreement. This is the third such agreement because the previous two in 2014 and 2015 were violated. Low-level fighting and artillery fire never fully stopped.
Voters in break away "people's republics" (Donetsk People's Republic and Lugansk People's Republic respectively) in Donetsk and Luhansk go to the polls for parliamentary and presidential elections. Rebel leaders Alexander Zakharchenko (Donetsk) and Igor Plotnisky (Luhansk) appear set for victory in early counting in elections which will be recognised in Russia but not elsewhere. International observers noted a very high turnout.
Ukrainian government forces recapture control of Yasynuvata from pro-Russian insurgents; government troops have now all but encircled the rebels' second-largest stronghold of Luhansk, and rebels declared a "state of siege" in Donetsk.
A large skirmish occurs in eastern Ukraine when pro-Russian separatists launch a massive attack on a border control centre near the city of Luhansk; five militants are killed and another eight are wounded, and seven Ukrainian border guards are wounded in the clash.
