Russo-Ukrainian War: The Battle of Sievierodonetsk ends after weeks of heavy fighting with the Russian capture of the city, leading to the Battle of Lysychansk.

The Russo-Ukrainian War began in February 2014 and is ongoing. Following Ukraine's Revolution of Dignity, Russia occupied and annexed Crimea from Ukraine. It then supported Russian paramilitaries who began a war in the eastern Donbas region against Ukraine's military. In 2018, Ukraine declared the region to be occupied by Russia. These first eight years of conflict also included naval incidents and cyberwarfare. In February 2022, Russia launched a full-scale invasion of Ukraine and began occupying more of the country, starting the biggest conflict in Europe since World War II. The war has resulted in a refugee crisis and hundreds of thousands of deaths.

The battle of Sievierodonetsk was a military engagement in the wider battle of Donbas of the eastern Ukraine campaign during the Russian invasion of Ukraine.

The battle of Lysychansk was a military engagement between Russia and Ukraine in the wider battle of Donbas of the eastern Ukraine campaign during the Russian invasion of Ukraine. By May 2022, Lysychansk and its twin city of Sievierodonetsk were the two largest cities of the Luhansk Oblast not under Russian control. Russian forces launched an assault on Sievierodonetsk in May where a fierce battle occurred until late June, when Ukrainian forces withdrew from the city. Fighting then continued as Russian forces started to attack Lysychansk across the Donets River.

June 25 is the 176th day of the year in the Gregorian calendar; 189 days remain until the end of the year.
