A spokesman for the Pakistani military says the country's powerful spy chief is on his way to Washington.
Lt. Gen. Ahmed Shuja Pasha's trip comes amid Pakistani fury over the unilateral May 2 U.S. raid that killed Osama bin Laden in the Pakistani garrison town of Abbottabad.
Pasha heads Inter-Services Intelligence, a powerful military-run spy network that has been an uneasy ally to the U.S. in the battle against Islamist militants.
Although he was reportedly angry at being left out of the loop on the U.S. raid on the al-Qaida chief, his trip could signal attempts to improve ties.
Army spokesman Maj. Gen. Athar Abbas gave no details about the visit on Wednesday.
