Watch: Footage shows last residents' struggle to leave Ukraine town

Few people remain in Avdiivka, a town on Ukraine's front line that is bombed relentlessly by Russia.

Its pre-war population was more than 30,000. Now, there are just over 1,000 left. Many have fled and many have been killed.

Amid the thud of explosions and rattle of gunfire, a special police unit called the White Angels goes door-to-door helping to evacuate the town's remaining civilians.

Footage the unit has shared with the BBC shows the desperate conditions those remaining must endure, and how hard it is to leave under constant bombardment.

The officers have to try to convince people to get out, but some refuse - they say they have nowhere else to go.

The BBC's Abdujalil Abdurasulov has been examining the footage.
