Amidst thickly forested mountains, we're driving into the base of the Chin National Army, which is the biggest rebel group that is fighting in Myanmar's western Chin state against the military junta.

We're driving through winding roads and I can just see the camp beginning to appear through thick green trees.

We've just arrived at the hospital at the rebel base.

And you can really see the impact of the ferocity of the battle that is taking place on the front lines here.

I've just entered one of the rooms.

There are 10 beds in front of me, all of them full.

And on many of them, I can see people who've had limbs amputated.

He's had his left leg amputated.

He was brought in here just last night with four other rebel fighters.

They were also attacked by drones.

So he's got injuries on the upper part of his body as well.

On a bed across from Sisi Mong is Van Nye Thang.

He used to work in the government until the coup.

Then he joined the resistance.

He tells us the junta is pushing to recapture territory ahead of the election.

But he and other fighters are determined not to let that happen, despite the personal cost to them.

Chin groups say at least three schools and six churches have been targeted since October.

In videos verified by the BBC, explosions can be heard as the body of seven-year-old Zohan Punlianchung is carried by his weeping brother, as he and other villagers flee their homes.

Zohan and 12-year-old Zeng Charmui were killed in the attack on their school when they were attending lessons.

Their classrooms are destroyed.
