Washington: The US has expressed its full confidence in the organisation and its European allies to achieve its objectives in Libya following the reports that NATO is running out of ammunitions to fight the war in Libya.

“We believe that NATO has the capability and the capacity to fulfill the mission it has taken to lead, command and control in enforcing UN Security Council Resolution 1973," the White House Press Secretary Jay Carney told reporters at his news conference on Monday.

He said that the Obama administration has no plans to change its supportive role in Libya right now.

"We provide capacities for jamming, for tanker refuelling, for intelligence gathering and the like, and we continue to work with our NATO partners to find if there are other ways that we can assist," he said.

Demonstrating the capacity of NATO to fulfill its mission, Carney said that in the last 24 hours there has been a dramatic increase in the number of sorties flown by NATO planes as the weather has cleared.

The Pentagon on Monday said US continues to fly approximately seven to nine sorties per day. Over the weekend, there were three strikes by F-16CJs in support of this mission.
