Macedonian police drive back thousands of angry migrants with tear gas as they seal the border with Greece. Sean Carberry reports.
STORY: Macedonian riot police clashed with an angry crowd of migrants, and more than 1,000 migrants are being kept in no-man's land between Macedonia and Greece. They are among a massive influx of refugees from the Middle East, Africa, and Asia who've been crossing from Greece into Macedonia... and the Balkan country is now cracking down. Authorities say that while official border crossings will remain open, they are going to "reduce illegal border entry to a minimum". Macedonia has declared a state of emergency and is deploying army troops to border regions. Meanwhile, Petros Mastakas with the UNHCR is calling for more humanitarian assistance for migrants in limbo on the Greek side of the border. (SOUNDBITE) (English) UNHCR ASSOCIATE PROTECTION OFFICER, PETROS MASTAKAS, SAYING: "There are hundreds of vulnerable persons, children babies, other persons with extreme vulnerabilities including medical needs. Most of them, if not all of them stay rough in the open air. We do appeal to the Greek authorities to take all necessary measures to address humanitarian needs of the persons gathered on the border line." Some 50,000 migrants arrived in Greece in July alone, and many try to press north through Macedonia to reach Serbia and then enter the EU in Hungary. But here, as authorities crack down, it appears that a new front line is opening up in Europe's migrant crisis.
