Around 7,600 migrants entered Macedonia in just 12 hours overnight -- a record according to a UN official quoted by Macedonia's state news agency Friday.

"Around 7,600 migrants, mostly from Syria, entered Macedonia between 6:00 pm Thursday and 6:00 am today," Alexandra Krause of the UNHCR refugee agency told MIA. "We have information from our Greek colleagues that more migrants are travelling towards the Macedonian border in buses," she added.
