Nato lacking strike aircraft for Libya campaign

David Cameron has pledged four more British Tornado jets on top of eight already being used for the air strikes. But pressure is growing for other European countries, especially France, to offer more after the Americans withdrew their attack aircraft from the campaign on Monday.

"We will need more strike capability," a Nato official said.

Since the French launched the first raids on Libya 16 days ago, the coalition and Nato have destroyed around 30% of Gaddafi's military capacity, Lieutenant General Charles Bouchard, the Canadian officer leading the air campaign, told Nato ambassadors.

But attempts to "degrade" the Libyan leader's firepower further were being complicated by a shift in tactics by Gaddafi, said Brigadier General Marc van Uhm, a senior Nato military planner.

"They are using light vehicles and trucks to transport," while hiding tanks and heavy weapons, he said.
