Migrants wait in line to have errors in their transit documents corrected by Greek authorities at a camp in Idomeni, on the Greek-Macedonian border on Wednesday, March 2, 2016. Errors in recording the date of birth have led to dozens of migrants being prevented from crossing into Macedonia. Greek police said up to 10,000 mostly Syrian and Iraqi refugees were stuck at the country’s Idomeni border crossing in deteriorating conditions. (AP Photo/Petros Giannakouris)
