The Battle of Vescera (modern Biskra in Algeria) is fought in 682 or 683 between the Berbers of king Kusaila and their East Roman (Byzantine) allies from the Exarchate of Carthage against an Umayyad Arab army under Uqba ibn Nafi (the founder of Kairouan).
Uqba ibn Nafi had led his men in an expedition across north Africa, eventually reaching the Atlantic Ocean and marching as far south as the Draa and Sous rivers.
On his return, he is ambushed by the Berber-imperial coalition at Tahuda south Vescera, defeated and killed.
As a result of this crushing defeat, the Arabs are expelled from the area of modern Tunisia for a decade.
