Members of the Greek police deployed in Idomeni, on Monday were forced to use tear gas after a group of disgruntled migrants attacked and demolished a police van.
Migrants threw stones and broke the windscreen of the police vehicle, so the police had to react and disperse them.
Earlier, at the Greek-Macedonian border a migrant was injured. Greek authorities informed that it was a Kurd aged 40, who was wounded in the head.
So far, the circumstances in which the person was wounded in the camp Idomeni are not known.
