Macedonian police have fired tear gas to disperse around 50 migrants stranded in Greece who tried to pull down part of the razor wire fence separating the two countries.

Tensions have boiled over at the makeshift migrant camp near the border town of Idomeni, where more than 10-thousand migrants and refugees have been stranded since February. Our correspondent Kate Parkinson reports.

It is likely that the violence on the Greece-Macedonia border on Wednesday will likely happen again. There are a lot of people in this camp who are very frustrated. They are desperate.

The European Commission also wants Greece to set up border controls here on its northern border with Macedonia with Europe's border control agency Frontex, to stop the kind of violence that we saw here on Wednesday.
