The head of Pakistan's intelligence agency is visiting his counterpart at the CIA at a time of tension in the counterterrorism partnership between the two spy agencies.
The Inter-Services Intelligence (ISI) did not release details on the trip of Ahmad Shuja Pasha to the United States.
The cooperation between the ISI and the CIA reportedly has recently been disrupted by the case of a CIA contractor who shot dead two Pakistanis in the eastern city of Lahore in January.
Pakistan held Raymond Davis despite U.S. insistence he had diplomatic immunity.
He was released last month after the families of the dead men were paid compensation.
