“One soldier was fatally shot,” the Ukrainian army said in a statement, accusing the separatists of carrying out three attacks in the past 24 hours.
Since 2014, Ukraine has been at war with pro-Russian separatists who control parts of the territory in the east of the country and who are, according to Kiev, financially and militarily supported by Moscow.
This is the first death of a military man since a new ceasefire established last month for a conflict that has killed more than 13,000 people since 2014, according to Agence France-Presse.
Relations between Ukraine and Russia are currently at a peak of tension.
This climate was aggravated by the denunciation by the Ukrainian authorities of the presence of tens of thousands of Russian soldiers on the Ukrainian borders, suggesting an imminent invasion. In 2014, Russia annexed the Ukrainian province of Crimea.
Moscow denies any intention of war and says it has been threatened by “provocations” from Kiev and NATO, having presented, in early December, proposals for the Atlantic Alliance not to admit Ukraine and other countries in the Soviet area of influence as its members and withdraw your military detachments in Central and Eastern Europe.
The US and European allies have been threatening Russia with unprecedented and harsh sanctions if it attacks Ukraine.
US President Joe Biden will speak with his Ukrainian counterpart Volodymyr Zelensky on Sunday after he warned Russian leader Vladimir Putin on Thursday against any attempt to invade the country, the White House announced.
