WASHINGTON - The NATO will continue to lead the military operations on Libya while the US will retain the role to "support and assist," the White House said on Monday.

When asked if the administration is considering taking up a larger role as NATO is reportedly "running out of munitions," White House spokesman Jay Carney said that NATO has "the capability and the capacity" to fulfill the mission, and to "take the lead in command and control."

He said the role of the US will still be, as promised by President Barack Obama, to "support and assist."

"We provide capacities for jamming, for tanker refueling, 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 added.

Carney insisted that the US has no plans to change its " posture."

Less than a month into the Libyan conflict, NATO is running short of precision bombs, highlighting the limitations of Britain, France and other European countries in sustaining the military action, a Washington Post story said on Friday.
