UNHCR spokesman Babar Baloch says the UN agency is hearing "worrying reports" that the Macedonian authorities are "only allowing people from Syria or Iraq" to cross the border at the Idomeni camp on Greece's northern border with Macedonia.
Around 14,000 people are currently stuck on the Greek side of the border at Idomeni after Macedonian authorities started limiting the number of people they would let through to just a few hundred a day.
There have been violent clashes at the crossing in the past week with a crowd of chanting migrants trying to force their way through the border fence using a metal sign post as a battering ram.
Macedonia today imposed further restrictions only allowing Syrians from parts of the country they consider to be at war to enter.
It means people from cities such as Aleppo could cross, but those from the capital of Damascus would be stopped; Dailymail reported.
