Sky news:
Released Ukrainian prisoner of war reveals torment at the hands of Russians
Recent deals with Russia saw the release of 215 Ukrainian prisoners of war. Speaking for the first time to Sky's Sally Lockwood, one former marine tells of being treated "like animals" - stripped, beaten, duct-taped, shocked and humiliated.

When Ukrainian marine, Mikhailo Dianov, was released from Russian detention, his photo shocked the world.
His body was emaciated after four months as a prisoner of war.
When I met him, he was unrecognisable from the photos I'd seen of the well-built fighter in Mariupol, Ukraine. His clothes hung from his frail frame. His gaunt face seemed far older than his 42 years.
I had so many questions. Crucially, did you worry you wouldn't survive?
"We thought about this every day," Mikhailo tells me. "We first started having those thoughts at the Azovstal steel plant.
"At Azovstal we thought it was the end."
Mikhailo was taken following weeks
under siege in Mariupol defending the steel works. It was the last corner of the city to fall in May.
He was among 215 recently released in a high-profile prisoner swap with Russia and spoke exclusively with Sky News about captivity.
"Believe me, after a month of being starved, when you close your eyes, you forget about your family, about your country, about everything. The only thing you think about is food."
'They treated us like animals'
Mikhailo lost 40kg (more than six stone) in weight in his four months as a prisoner of war.
"It was impossible to eat. You were given 30 seconds for each meal," says Mikhailo. "In 30 seconds you had to eat everything you could.

"Bread was deliberately very hard. Guys who had their teeth knocked out couldn't manage to eat in time.
"It was 30 seconds, and then you had to stop. Then you had to get up straight away and run. It was like that all the time.
"They treated us like animals."
The meals sound pitiful, and the process of eating utterly humiliating.
This all took place in the Olenivka prison in Russian-controlled Donetsk - a place Mikhailo refers to as a concentration camp.
It clearly seems prisoners of war being held there are being starved deliberately.
