Tensions between migrants stranded on the Greek side of the Greek-Macedonian border and Macedonian police have subsided. Greek police forces didn't actively intervene in the clashes, but positioned themselves between the migrants and Macedonian police to protect the latter, as the migrants would not throw stones at the Greeks. Macedonian police have charged into Greek territory after an estimated 250 or more asylum-seekers began pelting the police with rocks. A Macedonian army spokesman, who spoke on condition of anonymity because he was not authorized to comment before an official statement is released, confirmed the operation on Saturday but declined to provide details. Greek police say about 800 migrants are stranded on the Greek side in worsening weather after Macedonia blocked access to citizens of countries that are not being fast-tracked for asylum in the European Union.
