NATO's top decision-making body is set to decide whether the alliance will join in the strikes on Libya.
Diplomats said NATO's military planners are due to present final action plans to the North Atlantic Council on Sunday. The body should then decide whether the alliance will join the coalition operation or just provide logistical, intelligence and other support to the nations taking part in the intervention.
Several NATO governments have indicated they would not participate in aerial attacks, pointing out that the alliance is already heavily engaged in the war in Afghanistan.
U.S., French and British forces began pounding Libyan targets on Saturday following an emergency summit in Paris. U.S. officials say nearly two dozen targets were struck.
