The Tajbeg Palace assault, known by the military codename Operation Storm-333, was a military raid executed by the Soviet Union in Afghanistan on 27 December 1979. Special forces and airborne troops stormed the heavily fortified Tajbeg Palace in Kabul and assassinated Afghan leader Hafizullah Amin, a Khalqist of the People's Democratic Party of Afghanistan (PDPA) who had taken power in the Saur Revolution of April 1978. It was the start of the Soviet–Afghan War.
