BENGHAZI, Sept 11 (Reuters) - Authorities in eastern Libya said at least 2,000 people were killed and thousands more were missing after a massive flood ripped through the city of Derna following a heavy storm and rain.

The head of the Red Crescent aid group in the region had earlier on Monday said Derna’s death toll was at 150 and expected to hit 250. Reuters could not independently verify either figure.
