Assassination of Taraki
After Taraki returned to Kabul he requested that Amin meet with him. Amin agreed to the meeting only if his safety was guaranteed by the Soviet Ambassador, Alexander Puzanov. Such assurances were provided, but not in good faith.
Amin however knew Taraki's intentions, and the demand for the ambassador to guarantee his safety was probably a shrewd ploy on the part of Amin to mislead Taraki.
When Amin arrived at the People's Palace, a shootout occurred. Amin escaped unhurt, returned later to the palace with some of his supporters and used the Palace Guard to take Taraki prisoner.
On September 14, 1979 Amin took control of the government. A few days later, Amin's government announced that Taraki died of an "undisclosed illness".
