Libyan rebels say 13 killed in NATO airstrike

The main Libyan opposition spokesman says 13 rebels have accidentally been killed and seven injured in a NATO airstrike targeting Moammar Gadhafi's forces.

Abdel-Hafidh Ghoga said Saturday that the attack occurred as the rebels prepared to take over the oil city of Brega.

His comments are the first confirmation that the rebels were killed in an airstrike. NATO says it's looking into the report.

Calling it an "unfortunate accident," Ghoga says the rebels were killed as they moved forward while the NATO strike was in progress late Friday.
