ISLAMABAD: An official with Pakistan's top intelligence agency is denying it helped unmask the CIA's Islamabad station chief, who was forced to leave the country after threats were made to his life.

A Pakistani lawsuit revealed his name, and questions have arisen about whether a US lawsuit filed last month in connection with the 2008 Mumbai attacks raised tensions with Pakistan and spurred it to retaliate.

But the official insisted Saturday his agency played no role in the station chief's exposure in connection with the US lawsuit or for any other reason.

He requested anonymity because he lacks clearance to speak to media on the record.
