Britain said it will add more bombs to the weapons its warplanes are carrying which will be a strong message to the Libyan leader to force him end his rule.

NATO Secretary-General Anders Fogh Rasmussen said on Monday NATO's military campaign in Libya is progressing and Muammar Gaddafi’s is sure to go, a Reuters report said.

The army, over the months, has faced serious problems trying to conclude General Gaddafi’s hold despite bombarding the city for weeks through air strikes and rebel uprisings.

NATO warplanes have increased their air strikes on Tripoli and have constantly hit Gaddafi's Bab al-Aziziyah compound in the heart of the city.
