Survivors of Typhoon Haiyan are becoming increasingly desperate in their search for food and water, a missionary has told the BBC.

Kevin Vacca, originally from Austin, Texas, has lived and worked in the Philippines for 14 years.

He told the BBC the situation was "very dangerous" and could get worse, with reports of looting and buses being attacked.
