Refugees from Iraq warm themselves next to a makeshift fire, as they wait to be allowed to cross the the Greek-Macedonian border near the northern Greek village of Idomeni, Wednesday, Feb. 24, 2016. The Greek interior ministry said about 12,000 people have been stranded in Greece since neighbor Macedonia began turning Afghan immigrants away at the border and slowing the number of crossings for others heading to central and northern Europe.
