The 19-year-old man, whose injury was described as not life-threatening, was hospitalized early today and told police he had been attacked by another Pakistani migrant who hasn't been identified, authorities said.
About 300 people are staying at the makeshift camp that sprung up near the border last week after the government cleared a huge settlement in the area.
Also today, four Syrian men were hospitalized with minor injuries after a fight broke out at a government shelter for migrants in northern Greece.
