TRIPOLI (AFP) – NATO's chief will hold talks on Libya with British leaders on Wednesday after the alliance battered Moamer Kadhafi's forces even as its top brass raised concerns about the 11-week aerial war.

NATO Secretary General Anders Fogh Rasmussen will meet in London with British Prime Minister David Cameron and Foreign Secretary William Hague for discussions on the military operation.

The talks come as rebels fighting to end Kadhafi's four decades of autocratic rule won more diplomatic recognition and seized Al-Rayayna village, east of the heavily fought-over hilltown of Zintan southwest of Tripoli.

"The fighting here has become even fiercer because the rebels have become stronger but things move slowly," a witness in Zintan told AFP.
