Libya’s rebels said Friday they have reports that Moammar Gadhafi’s youngest son, who commands one of the regime’s strongest military brigades, was killed in a NATO airstrike in the western town of Zlitan.

NATO said in a statement that it was aware of the reports that Khamis Gadhafi had been killed, but it did not confirm his death. It said alliance strikes on Thursday night hit an ammunition depot and military police facility in Zlitan, which is the main front of fighting between rebels and Gadhafi’s troops, 90 miles (140 kilometers) southeast of Tripoli.
