Migrant crisis: Clashes as Macedonia erects border fence

Macedonia has become the latest country to restrict the flow of migrants entering the country, erecting a fence on its border with Greece.

The International Organization for Migration (IOM) says 105,000 migrants have passed through Macedonia from Greece in November alone.

Clashes have been reported between some of those stuck at the border and police, while a number of Iranian men have sewn their lips shut in protest at not being allowed to continue.
