Anushtakin was arrested in Ascalon, then imprisoned in Cairo.[25] His dismissal left the Bedouin alliance in virtual control of Syria.[25] Anushtakin was ultimately released upon the intervention of Sa'id al-Su'ada, a senior eunuch of az-Zahir.[25] Despite his distance from events, Anushtakin remained privy to developments in Palestine and Syria.[2] Al-Rudhbari was replaced as vizier by Ali al-Jarjara'i in December 1027/January 1028 and in November 1028, he assigned Anushtakin to lead a military expedition against the Tayy in Palestine;[26] by then, the Kalb had defected to az-Zahir, weakening the Bedouin alliance and giving the Fatimids an opportunity to reassert their authority in Syria.[26]
