Three 18-year-old Afghan migrants have been jailed for gang-raping another teenage boy living in the same Austrian asylum centre.

They were sentenced in the Austrian city of Salzburg to terms in jail ranging from two to three-and-a-half years each.

The court heard how they used intimidation to force their victim to perform sex acts with each of them in March.

All four, the three attackers and their victim, were living in the same asylum centre in the town of Tennengau in the state of Salzburg at the time of the incident.

The sexual abuse took place in a cave just outside the facility after the three threatened they would kill the boy with a sharp piece of glass unless he went with them. The Afghan victim eventually reported the incident to the police.

During the trial, the defendants claimed that the sex acts were carried out with the teenager's consent.

The first of the defendants justified his actions in front of the court by claiming the Afghan boy wanted 10 euros per person to carry out the acts.

One of the defendants said: 'We were drunk. I had some homosexual experiences before. When the offer came, I was immediately attracted to it.'
