Migrants clashed with Macedonian police Sunday after trying to scale the fence separating Greece from Macedonia in the border town of Idomeni. Macedonian police used tear gas, stun grenades, plastic bullets and later a water cannon in attempts to keep the migrants at bay and they responded by throwing rocks at the police. Twice, migrants tried to breach the fence but were pushed back. Greek police were standing by, not interfering. Clashes continued into the afternoon, and the wind brought tear gas fumes into a nearby makeshift camp on the Greek side of the border holding over 11,000 stranded migrants. Many people, including small children, who were not involved in the clashes, were suffering from respiratory problems, AP reported.
