TRIPOLI, Libya - A Libyan rebel spokesman has dismissed the cease-fire announcement, claiming Moammar Gadhafi's forces are still attacking key cities in the east and the west.

Facing Western military action, Libya's Foreign Minister Moussa Koussa announced Friday that the government will stop all military operations.

But Mustafa Gheriani, a spokesman for the national opposition council based in Benghazi, says "no cease-fire."

Gheriani says regime forces are shelling the eastern city of Ajdabiya and Misrata, the last rebel-held city in the western half of the country.

Western powers are racing to prevent more attacks after the U.N. Security Council passed a resolution setting the stage for airstrikes, a no-fly zone and other military measures short of a ground invasion.
