Watch: Ukrainian Soldier Performs 'Pikachu Dance' While In Camo, At Battlefield

A video shared by the Ukrainian military showing a person who appeared to be a Ukrainian soldier dancing has gone viral.

The 23-second video, which was uploaded by the Twitter account of Ukraine's Ministry of Defense (MOD) Monday, featured an unidentified person dancing to a song while dressed in full combat uniform, even as explosions are heard in the background.

"Morning Pikachu Dance. Winter has never been an obstacle to a good mood," the ministry said in its post.

Pikachu is a yellow, mouse-like creature in the "Pokémon" franchise.

The MOD's clip has received more than 13,000 retweets and 64,000 likes as of writing.

Ukraine's defense ministry shared a similar video Sunday that showed a Ukrainian soldier dancing on top of a vehicle as club music plays.

"Morale is high," the ministry wrote alongside the video.

Despite being subjected to Russian missile and drone strikes, around 86% of Ukrainians believe it is necessary to continue fighting back against Russia's unprovoked invasion, a survey conducted in October found.

Russia's attacks, which hit civilian buildings and energy infrastructure, have left millions in Ukraine without electricity, heating or water.

At least four people were killed in the most recent wave of strikes Monday, Ukrainian President Volodymyr Zelensky said.

Hundreds of hospitals and healthcare facilities are also "no longer fully operational" or lacking supplies to meet basic needs as a result of Russia's attacks, according to Dr. Hans Kluge, the World Health Organization's regional director for Europe.

"This winter will be life-threatening for millions of people in Ukraine," Kluge said.

The "extensive destruction and appropriation of property, not justified by military necessity and carried out unlawfully and wantonly," is considered a war crime under the Rome Statute of the International Criminal Court.

Russia has repeatedly dismissed allegations that its forces deliberately targeted civilians.

U.S. officials pledged last week to give Ukraine $53 million for the repair of the country's damaged electrical grid.

Ukraine has also received air defense systems from various nations in the face of continued Russian attacks, including the National Advanced Surface-to-Air Missile System (NASAMS) from the U.S., Aspide from Spain and IRIS-T from Germany.

"These weapons will significantly strengthen [the Ukrainian Army] and will make our skies safer. We will continue to shoot down the enemy targets attacking us," Ukrainian Defense Minister Oleksii Reznikov said when the first NASAMS arrived in Ukraine last month.
