Only a few people remain in Avdiivka, a front-line town in Ukraine that is under relentless Russian bombing.
Its population before the war was more than 30 thousand people. Now, there are only a little over 1,000 left. Many have fled, and many have been killed.
Amid the sound of explosions and the sounds of gunfire, a special police unit called the “White Angels” goes door to door to help evacuate the city's remaining civilians.
Footage the unit shared with the BBC shows the desperate conditions those remaining must endure, and how difficult it is to leave under constant bombardment.
Officers try to persuade people to come out, but some refuse – saying they have nowhere else to go.
BBC correspondent Abdul Jalil Abdul Raslouf examined the footage.
