A Pakistani intelligence official said yesterday that an American in custody for killing two men was an undercover CIA contractor, in remarks likely to inflame a crisis with the United States. Washington insists that Raymond Davis, who says he acted in self-defence, is a member of its Islamabad embassy's "administrative and technical staff" who has diplomatic immunity and should be released immediately. But the unpopular government in Pakistan is under huge pressure from the political opposition not to cave in to US demands, with analysts even warning that the case could bring down the ruling Pakistan People's Party (PPP). "It is beyond any shadow of a doubt that he was working for CIA," an official from Pakistan's Inter-Services Intelligence (ISI) agency told AFP on condition of anonymity. "He's on contract. He's not a regular CIA guy, but he's working for CIA. That's confirmed," the Pakistani official said. Pakistan's powerful intelligence services and military have been angered by accusations that they support Taliban and Al-Qaeda-linked networks fighting US troops in Afghanistan, and need to do more to eliminate Islamist militants.
