Ukraine has said one of its soldiers has been killed in fighting with pro-Russian separatists in the east of the country, as tensions with Moscow rise.
Kyiv has been battling a pro-Moscow insurgency in two breakaway regions bordering Russia since 2014, when the Kremlin annexed Ukraine's Crimean peninsula.
Russia has mass troops near Ukraine's borders, and the west has accused it of planning an invasion and threatened Moscow with massive sanctions should it launch an attack.
The Ukrainian army said separatists had targeted its positions with grenade launchers and mortars. One serviceman was killed and another was injured, it said.
Kiev and its allies accuse Russia of supporting the rebels militarily, claiming Moscow denies.
The latest death brings Ukraine's toll in the simmering conflict to 65 since the beginning of the year, according to official figures, compared to 50 in 2020.
Russia has about 100,000 troops on its side of the border. Joe Biden warned Vladimir Putin of the sanctions like he has never seen if the troops attack Ukraine. On Thursday, European Union leaders urged Moscow to halt its military buildup and return to talks led by France and Germany.
More than 13,000 people have been killed in eastern Ukraine as a result of the conflict.
