With Operation Storm-333 in December 1979, the Soviet Union launched a full-scale invasion of its central Asian neighbor and installed Babrak Karmal as the Afghan head of state. The invasion caused widespread opposition and panic, with armed Afghan mujahideen fighters gearing up a war against the Red Army. Meanwhile, opposition and unrest also occurred in urban areas, most notably in Kabul when thousands of residents rose up in February 1980 in the uprising of 3 Hoot, challenging the authority of the People's Democratic Party of Afghanistan.
