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.
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.
Pro-Russian separatists continue to control the strategic border crossing near Izvaryne, Luhansk Oblast, which they are believed to use to transport weapons and reinforcements from Russia into Ukraine.
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.
At least thirty pro-Russian separatists have died in fighting over control of Donetsk International Airport; the Ukrainian government claims to have total control of the airport following the clashes with the separatists.
Ukraine's Deputy Prime Minister Vitaly Yarema announces that pro-Russian militants will be targeted in four eastern cities, Kramatorsk, Slaviansk, Donetsk and Luhansk, as they refuse to vacate government buildings they previously seized, defying the international deal made in Geneva.
Russia and Ukraine together with the United States and the European Union sit down for emergency talks in Geneva. All four agree that "illegal military formations in Ukraine" must be dissolved, and that everyone occupying buildings must be disarmed and leave them. There would be an amnesty for all anti-government protesters under the agreement.
