Devastation after Philippines floods on Mindanao

A mass burial has been organised in the Philippines for scores of people killed by flash floods on the southern island of Mindanao.

Footage from the area shows large-scale devastation in the coastal communities that were hit by flash floods triggered by a tropical storm on Saturday.

More than 650 people were killed and another 800 people are still missing.

Angela Travis, a spokesperson for the UN children's agency Unicef, said that clean water and sanitation were key concerns as many people were left homeless and without essential supplies after the storm.
