A British man who was captured by Russian forces when fighting in Ukraine said he was kept in solitary confinement and beaten if he didn't sing the Russian anthem.
When Ukrainian troops were besieged in the city of Mariupol, Aslin was forced to surrender to the Russians in April.
He was released in a prisoner swap last week after being held in a detention center.
In his first interview since being freed, Aslin said that he was kept in solitary confinement for five months and was treated worse than a dog.
Aslin said that his cell was full of pests.
According to The Sun, Aslin said he was forced to sing the Russian national anthem every morning and yell "Glory to Russia" whenever a guard approached his cell.
He would be punished if he didn't comply.
One of the Russian officers threatened to cut off Aslin's ear and he was repeatedly beaten with a baton.
He realized he had been stabbed when the officer showed him the knife.
He wanted to know if I wanted a quick death or a beautiful death. On Sunday, Aslin spoke to The Sun.
I said 'A quick death'. He smiled and said that he would make sure it was a beautiful death.
Russian authorities freed 10 international prisoners of war, including Aslin, after a deal was brokered by Saudi Arabia and Russian billionaire Roman Abramovich.
Five of the prisoners, including Aslin, were British, two were American, one was American, and the other was Swedish.
The whole experience was very scary according to another British fighter who was released with Aslin.
In an interview with The Sun on Sunday, Aslin said that he was treated worse than a dog and that he was on a plane with people who didn't want to hurt him.
Aislin was born in the UK but moved to Ukranian in order to meet his girlfriend.
He enlisted in the Ukrainian army after Russia invaded the country.
He fought with the Kurdish People's Protection Units in Syria.
