- Battle of Marash: Emir Sayf al-Dawla marches north into the Byzantine Empire and ravages the countryside of Malatya (modern Turkey). On his way back, he crosses the Euphrates and intercepts a Byzantine army led by Bardas Phokas (the Elder), near Marash. The Byzantines are defeated; Bardas himself barely escapes through the intervention of his attendants. His son Constantine Phokas, governor of Seleucia, is captured and held prisoner in Aleppo until his death of an illness some time later.
