Dozens of migrants stranded on Greece’s northern border with Macedonia hurled stones at police, a Reuters witness said, after one man living in the sprawling tent city near the town of Idomeni was injured by a police van.
Police fired teargas to break up the crowd.
Some migrants said the man had fainted as he left his tent and was then hit by the van. A small pool of blood could be seen on the ground. The man was taken to a local hospital and was not seriously hurt, Greek media said.
It was not immediately clear what caused the accident.
