In 1024, one of Hassan's sons and another Bedouin chieftain sacked Ayla and al-Arish, which the Fatimid central government was unable to respond to.[14] Instead, Anushtakin took the initiative to extract taxes from Hassan's iqtaʿ at Bayt Jibrin and deprive him of the revenues, which ended with the killing of Anushtakin's soldiers.[15] This escalated the conflict with the Jarrahids, particularly after Anushtakin imprisoned two of Hassan's chief aides in Ascalon.[15] The Jarrahids launched an all out war in September to release their men, destroying Tiberias, besieging Ramla and freeing their men by forging release authorization documents.[15] They forced al-Dizbari to flee Ramla, which they plundered, and gained a Fatimid concession to grant Nablus as an iqtaʿ, but not Jerusalem.[15]
