Pakistan may continue its blocking of Nato convoys into Afghanistan for weeks, Prime Minister Yousuf Raza Gilani has toldthe press.
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.
He also denied rumours President Asif Ali Zardari had suffered a stroke and the army was trying to oust him.
Mr Gilani said Mr Zardari was making a rapid improvement in hospital in Dubai, but would need two weeks’ rest before returning home.
