Children play in 'toxic' foam blanketing Indian beach

Children have been seen playing in a strange wave of white foam which has washed up on Marina Beach in Chennai, India over the weekend.

Locals, however say the foam is toxic, caused by pollutants in sewage mixing with sea water, the BBC reports.

A local pollution control officer told the Indian Express newspaper that authorities hoped the pollutants in the water should subside in the next couple of days.
