BBC News with Marion Marshall

The Pakistani Prime Minister Yousaf Raza Gillani says his country doesn't trust the United States and the feeling is mutual. Mr Gillani told the BBC it could be weeks before Pakistan lifts its blockade of Nato convoys carrying supplies to Afghanistan. Relations between the US and Pakistan have been in crisis since 24 Pakistani soldiers were killed in a Nato air strike on two border posts last month. Mr Gillani said relations with the US must be improved.

"Yes, there is a credibility gap. We are working together, and still we don't trust each other. I think we have to improve our relationship so that for the better results we should have more confidence in each other."
