Thousands of mourners packed the village of Pawakal, outside Peshawar, for the funeral prayer, the Pakistan Tribune reported. Former and present politicians gathered in the Ladies Club for the rite.
Khan, born in Northwest Frontier Province, joined the Indian Civil Service under British rule and continued to serve after the partition of Pakistan. From 1977 to 1985, he was federal minister for finance and then served as president of the Senate.
In 1988, when Gen. Zia ul-Haq was killed in a plane crash, Khan became caretaker president, later winning election in his own right. He dismissed the governments of Prime Minister Benazir Bhutto in 1990 and of Nawaz Sharif in 1993.
The latter action led to Khan's downfall when it was reversed by a court, and a military coup ousted both president and prime minister.
