Massive flash flood devastated the Libyan city of Derna, killing thousands and leaving 30,000 homeless.

International aid effort ramping up to provide food, water, shelter and supplies to survivors amid risk of disease.

Death toll uncertain but could be over 10,000; thousands more missing and bodies still washing up on shores.
