Ukrainian forces remain in control of the strategic railway hub of Debaltseve in the east of the country, despite intense shelling by rebels.
Government troops say they haven't suffered any casualties so far.
The commander of the 25th volunteer battalion "Kievska Rus", who goes by the name "Vysota," explains the situation.
