In the Balkans, there were scuffles between Macedonian police and migrants on the border with Greece, as they let through a trickle of people trying to head north through the Balkans to Hungary, a member of the Schengen free movement area and a major point of entry to the EU. Since the border was reopened following clashes over the weekend as police tried to keep out migrants, nearly 10,000 people have poured through the country and on into Serbia, including some pushed in wheelchairs and wheelbarrows, or moving on crutches.
