As Amin's rule progressed into the late 1970s, there was increased unrest against his persecution of certain ethnic groups and political dissidents, along with Uganda's very poor international standing due to Amin's support for the terrorist hijackers in Operation Entebbe. He then attempted to annex Tanzania's Kagera Region in 1978, so Tanzanian president Julius Nyerere had his troops invade Uganda; they captured Kampala on 11 April 1979 and ousted Amin from power. Amin went into exile, first in Libya, then Iraq, and finally in Saudi Arabia, where he lived until his death on 16 August 2003.
