 Ibrahim II then briefly named his own son as governor, before the appointment of the Sicilian Husayn ibn Rabah.Husayn renewed the campaigns against the remaining Byzantine strongholds in the northeast, especially Taormina, in 879–880, but without success.Indeed, the Byzantines were able to launch a limited counteroffensive in 880, when the admiral Nasar defeated an Aghlabid fleet in a daring night attack in the Ionian Sea, and then proceeded to raid the environs of Palermo, before defeating another Aghlabid fleet at the Battle of Stelai.
