US Senator McCain tours Benghazi

Libyan rebels in the eastern stronghold of Benghazi have been visited by the veteran US Senator John McCain.

His visit comes as Libya has accused Nato of killing nine civilians overnight.

The authorities say the victims were working at the water plant in the city of Sirte repairing earlier bomb damage.

Anti-Gaddafi forces have welcomed America's decision to send unmanned armed drones to join Nato's military operation.

From Libya, the BBC's World Affairs Correspondent Peter Biles reports.
