 The Byzantine fleet contested the passage of Abu'l-Aghlab's small fleet, which lost ships both to the Byzantine attack and to storms; the Byzantines however could not prevent it from reaching Palermo, and were driven off by a squadron from the city under Muhammad ibn al-Sindi.Abu'l-Aghlab avenged himself by launching naval raids against Pantelleria and other localities, beheading the Christians taken prisoner.At the same time, a Muslim cavalry raid reached the eastern parts of the island around Mount Etna, burning the villages and crops and taking captives.
