A trickle of refugees have been allowed to cross the border from Greece into Macedonia - the first for two days following clashes earlier this week.
Macedonia briefly opened the border crossing overnight, letting around 170 people cross, Greek Police said.
However some 10,000 people remain camped at the crossing, awaiting their turn.
It comes after clashes broke out on Monday as hundreds attempted to storm the border crossing.
A trickle of refugees have been allowed to cross the border from Greece into Macedonia - the first for two days.
Greek police said 170 people were allowed through at the Idomeni crossing when the Macedonian authorities briefly opened the border overnight.
However some 10,000 people remain camped at the crossing, awaiting their turn.
Hundreds, including many families with small children, arrive daily at the crossing in northern Greece, where two official camps are so full that thousands have set up tents in fields all around.
Macedonia has said it will only allow in as many refugees as Serbia, its northern neighbour, takes each day.
The tiny trickle has caused a huge backlog in Greece, where most refugees and other migrants reach Europe.
