A NATO official said on Friday that the alliance would take a new plan to step up strikes against pro-Gaddafi forces in Libya to protect civilians.

"Our campaign will now shift targets to hit more pro-Gaddafi troops pressuring civilian centres. You will understand that we cannot and will not disclose the plan; however you will see results in the next few days," Brigadier Rob Weighill, director of operations in Libya, said via video conference from Naples, Italy.

Weighill said that NATO had "halted the advance of pro-Gaddafi troops" and "seriously degraded command and control and logistics capabilities."

It has been one month since NATO assumed full command of the military campaign in Libya for the United States. However, there is still no end in sight as Libyan leader Muammar Gaddafi has shown no sign of giving in.

In his speech, Weighill also urged patience for NATO's operations, saying "it is important to remember that ours is a deliberate campaign, and campaigns take time."
