Operation Storm-333
Operation Storm-333 (Шторм-333, Shtorm-333) was the codename of an operation that took place on 27 December 1979, in which Soviet Union forces stormed the Tajbeg Palace in Afghanistan and captured Afghan President Hafizullah Amin. An unknown number of Afghan palace guards were killed while 150 were captured. Amin's 11-year-old son died from shrapnel wounds. The Soviets installed Babrak Karmal as Amin's successor.
Several other government buildings were seized during the operation, including the Ministry of Interior building, the Internal Security (KHAD) building, and the General Staff building (Darul Aman Palace). Alpha Group veterans call this operation one of the most successful in the group's history.
Background
The Democratic Republic of Afghanistan was initially led by Nur Muhammad Taraki, who was pro-Soviet Union, so Afghan–Soviet relations were friendly. In September 1979, Taraki was deposed by Hafizullah Amin, due to intra-party strife. After this event and the suspicious death of Taraki (an apparent assassination by Amin's followers), Afghan–Soviet relations started to deteriorate; by December the Soviet leadership had established an alliance with Babrak Karmal. The Soviet Union declared its plan to intervene in Afghanistan on 12 December 1979, and the Soviet leadership initiated Operation Storm-333 (the first phase of the intervention) on 27 December 1979.
