WASHINGTON (INP) - Ties between the intelligence agencies of Pakistan and the US have been severely strained since the killing of Osama bin Laden in a covert US raid in Pakistan in May. In an interview with VOA, US Ambassador to Pakistan Cameron Munter acknowledges that the bin Laden raid was a setback for bilateral ties. 'I think in the wake of what happened on May 2, there was a great deal of consternation on the side of Pakistan because of the issue of the sovereignty, the questions that were raised, Munter said. 'There were questions that were raised in the US because people did not know whether there was a role of Pakistani authorities in him being here. This was a source of great amount of unhappiness on both sides because there were questions that could not be answered, he added. Munter stated the two countries will be able to re-establish their anti-terror cooperation to where it was before Osama bin Laden raid.
