Libyan state TV said Saturday 15 people were killed in a NATO air attack on civilian sites in the costal oil city of Brega in Libya.

The state TV said the NATO attacked sites where there were civilian, like a bakery and a restaurant, without giving details when the bombardment took place, however, official Libyan Jana news agency said it was on Saturday.

NATO later rejected the report, saying it hit "military targets ".

The oil refinery town of Brega lies on the frontline between the rebel-held east and the government-held west.

The NATO has said it hit command-and-control sites belonging to Libyan government near Brega. The alliance accuses forces loyal to embattled leader Muammar Gaddafi of hiding in civilian buildings in Brega and used these buildings to stage attacks against rebels- held Ajdabiya and Benghazi.
