Iranian Kurdish fighters.

Shaho Bluri hopes to return home soon to honour all the dead.

One of your brothers was hung.

How many members of your extended family have been killed by the regime?

18.

Suddenly, the commander, Amjad Panahi, gets news of a strike on one of their bases, sparking fears of an attack at our location.

Spread out, he warns.

They're worried about too many people being in the same place and being a bigger target.

They've had some intelligence that there may be a drone strike.
