Ukraine war: Battle for the city of Bakhmut intensifies

Russian forces have stepped up their assault on the city of Bakhmut, which they have tried to capture for more than six months.

Ukraine believes they are pushing to take the Eastern city before the one-year anniversary of Russia’s invasion later this month.

The BBC's Orla Guerin has spoken to Ukrainian forces still holding the city – despite sub-zero temperatures and dwindling ammunition - as the Russians close in.
