Macedonia police fire grenades at migrants

Macedonian police special forces have fired stun grenades to disperse thousands of migrants stuck in a no-man s land at the border with Greece.

The move came a day after Macedonia declared a state of emergency on its borders to deal with a massive influx of migrants heading north to Europe.

The crowd of 3,000 migrants, who spent the night out in the open, made several attempts to charge police lines after the border was shut to crossings. At least four people were injured in the clash.
