A former army chief will become Pakistan's next ambassador to the United States, the foreign minister said Saturday. Jehangir Karamat will replace Ashraf Jehangir Qazi, a career diplomat who last month was chosen by the U.N. Secretary-General Kofi Annan as his special representative in Iraq. Foreign Minister Khursheed Kasuri told reporters that Pakistan has informed the U.S. government about its decision to appoint Karamat as ambassador and he would take up the post once his credentials were approved by Washington. Karamat served as the army chief from 1996 to 1998.
