Russia claims to have successfully fought off a “major Ukrainian offensive” in the city of Donetsk, according to reports from The Guardian and WION. The Ukrainian military reportedly launched the offensive last week, but the Russian military claims to have repelled the attack and killed hundreds of Ukrainian troops in the process.

The conflict between Russia and Ukraine has been ongoing since 2014, when Russia annexed Crimea from Ukraine. In recent months, the conflict has worsened, with both sides accusing the other of escalating the violence.

According to a report from Yahoo News, the war is now “arriving on Russians’ doorstep,” with civilian casualties and damage to infrastructure increasing in Russian cities near the Ukrainian border. The CNN report on the war notes that this conflict has claimed the lives of over 14,000 people, with both sides engaging in “heavy fighting,” shelling, and other violent incidents.

In the latest development, The Guardian reports that a Belgorod energy facility was set on fire, possibly by Ukrainian forces. The Russian military claims to have repelled the attack and is investigating the incident.

The situation remains tense, and both sides continue to accuse the other of aggression. As the conflict continues, it is likely that more casualties and damage will occur, and the international community will need to take action to bring an end to this violence.
