The Ukrainian troops in the area claim that an enemy reconnaissance group, reinforced with support rocket fire from the militant-controlled territory, was on a mission to infiltrate the attacked position, Ukraine Today reports.

Despite four Ukrainian soldiers being wounded in this shelling, some of the filmed troops are seen singing and telling jokes during the attack, knowing this day could very well be their last.
