Dozens of Syrian demonstrated outside the Iraqi Kurdish parliament on Thursday calling for six men held after the sexual assault of a teenage Syrian refugee to be executed.
The men, all Iraqis, were arrested after the 16-year-old girl was assaulted on the outskirts of the Iraqi Kurdish region's capital Arbil on Tuesday.
Police said three of the suspects had confessed to carrying out the assault.
A police statement said the girl had been walking to her family's home in Arbil after finishing work at a local supermarket when three men snatched her and took her to a farm on the outskirts of the city. Then they proceeded to assault her sexually, and called three other men who also took part. The six later abandoned the girl, who made her way back to the city and reported the incident.
Three men were arrested late on Wednesday and three others more on Thursday, and the case has been referred to the courts.
The assault is the most violent incident against a Syrian refugee to be reported yet.
