From the BBC:  Pakistan may continue its blocking of Nato convoys into Afghanistan for several weeks, Prime Minister Yousuf Raza Gilani has told the BBC.

Pakistan stopped the convoys in protest at US air strikes which killed 24 of its troops at two checkpoints on the Afghan border last month.

Mr Gilani refused to rule out closing Pakistan’s airspace to the US. . . .

"Yes there is a credibility gap, we are working together and still we don’t trust each other," Mr Gilani said.

"I think we have to improve our relationship so that… we should have more confidence in each other."

Nato forces in Afghanistan rely significantly on overland supply routes from the Pakistani sea port of Karachi, which enter Afghanistan through the Khyber Pass.
