The Libyan aircraft were also used against Chad as part of the Chadian–Libyan conflict, with strikes into western Sudan and Chad. Libyan Tu-22s flew their first mission over Chad on 9 October 1980 against Hissène Habré's forces near the Chadian capital of N'Djamena. Occasional bombing raids by small numbers of Tu-22s against targets in Chad and Sudan, including a raid on Omdurman in September 1981, which killed three civilians and injured 20 others, continued to be performed until a ceasefire was arranged in November 1981.
