Tear gas used on migrants in Kos

Migrants have clashed with police on the Greek island of Kos for a second consecutive day, as tensions build at a sports stadium where hundreds of people, including young children, have been waiting for official papers.

Police used tear gas to push back crowds of migrants to try to control the chaos.

The island's mayor has warned of bloodshed, unless the influx of migrants is brought under control - increasing numbers have been arriving on boats from nearby Turkey.
