Hafizullah Amin
During the funeral ceremonies for Khyber a protest against the government occurred, and shortly thereafter most of the leaders of PDPA, including Babrak Karmal, were arrested by the government. Hafizullah Amin, was put under house arrest, which gave him a chance to order an uprising, one that had been slowly coalescing for more than two years. Amin, without having the authority, instructed the Khalqist army officers to overthrow the government.
