Libyans from across the fragmented country have driven through old front lines, regardless of bitter enmities, to deliver aid to flood-stricken Derna this week, putting aside years of conflict between their divided leaders.

Inside Derna, where a torrent washed away whole districts on Sunday night after two dams collapsed under storm floods, volunteers from Misrata, Tripoli and Benghazi were distributing clothes and food packages on Wednesday and Thursday.

Thousands were killed in the disaster and many thousands more are missing, though estimates of the toll have varied widely, and large numbers of Derna residents have lost their homes and belongings.
