Desperate plight of stranded Rohingya Muslim migrants

The United Nations has accused countries in south east Asia of "incomprehensible and inhumane" treatment of around 6,000 migrants who are stranded at sea.

The migrants are mostly Rohingya Muslims, who face persecution in their native Myanmar and are not recognised as citizens of the country.

Thousands board smugglers' boats in search of a better life but many are now stranded at sea in desperate conditions, with countries such as Thailand, Indonesia and Malaysia turning most of them away.
