PESHAWAR, Pakistan -- Ghulam Ishaq Khan, who became Pakistan's president in 1988 after the death of his predecessor in a plane crash, died Friday following a bout of pneumonia. He was 91.
Mr. Khan died in the northern city of Peshawar, where he spent most of his life, said his son-in-law, Arfan Ullah Murwat.
A career bureaucrat, Mr. Khan was a close ally of military dictator General Zia-ul Haq and held the post of chairman of Pakistan's Senate in 1988 when Haq was killed in a plane crash in eastern Pakistan along with US Ambassador Arnold L. Raphel and several top Pakistani generals.
Mr. Khan worked alongside former prime ministers Benazir Bhutto and Nawaz Sharif but dismissed the governments led by both in 1990 and 1993 respectively on charges of corruption and mismanagement.
"He was an honest, upright person and dedicated to the services of Pakistan," President General Pervez Musharraf said, according to the state-run Associated Press of Pakistan.
The dispute between Mr. Khan and Sharif continued following a subsequent Supreme Court decision that reinstated Sharif's government. Eventually, Pakistan's powerful military intervened and forced Mr. Kahn to resign in 1993.
