An open casket, outdoor service was held in Kyiv’s Independence Square for Maj. Oleh Yurchenko, who was killed in Bakhmut on Jan. 2.

The latest package of U.S. military assistance was the biggest to date for Kyiv. For the first time, it included Bradley armored vehicles – known as tank-killers because of the anti-tank missiles they fire.

Kyiv has been pressing the U.S. for tanks, longer-range missiles, armor and air defense systems.

It was one of the deadliest attacks on the Kremlin’s forces since the war began more than 10 months ago.

Ukrainian officials allege Moscow is deliberately targeting civilians and critical infrastructure to create a climate of fear.

Ukraine is investigating over 58,000 killings, kidnappings, indiscriminate bombings and sexual assaults but most perpetrators are unlikely to be arrested.

Moscow has targeted Ukrainian power facilities and other key infrastructure in a bid to weaken the country’s resolve and force it to negotiate on Russian terms.
