Iran Update, December 31, 2023
We will resume publication of the Iran Update (Israel-Hamas War) on January 2, 2024.
Key Takeaways:
Israeli forces advanced into Beit Lahiya for clearing operations in the northern Gaza Strip. Palestinian militias attempted to defend against Israeli forces operating in Tuffah and al Daraj in Gaza City. Palestinian militias did not claim any attacks in Jabalia City and Sheikh Radwan neighborhood.
Palestinian militias are clashing with Israeli forces in al Bureij in the Central Governorate of the Gaza Strip.
Israeli forces continued clearing operations in Khan Younis for the fourth straight week as Palestinian militia fighters tried to defend against Israeli advances. Palestinian militias have sustained almost daily attacks on Israeli forces in Khan Younis since Israel forces advanced into the southern Gaza Strip in early December.
Israel has withdrawn five IDF brigades from the Gaza Strip, which is consistent with Israeli forces transitioning to a third phase of operations. The third phase will include the end of major combat operations, a “reduction in forces” in the Gaza Strip, the release of reservists, a “transition to targeted raids,” and the establishment of a security buffer zone within the Gaza Strip.
An unspecified Israeli intelligence officer told the Economist that most of Hamas’ command structure is “gone” and that Hamas is no longer operating as a military organization. CTP-ISW assesses that at least three of 30 Hamas battalions in the five brigades are combat ineffective, at least eight battalions are degraded, and at least 12 battalions are currently under intense IDF pressure.
An Israeli Army Radio correspondent reported that IDF sources believe the intensification of fighting on the ground in the Gaza Strip has contributed to a reduction in Palestinian rocket capabilities. Palestinian militias did not claim any indirect fire attacks into Israel from the Gaza Strip.
Israeli forces clashed with Palestinian fighters in six locations across the West Bank.
Iranian-backed fighters, including Lebanese Hezbollah, conducted four attacks from southern Lebanon into northern Israel. LH Deputy Secretary General Naim Qassem stated that LH will not allow displaced Israeli civilians to return to their homes in northern Israel until Israel halts its military operations in the Gaza Strip.
Iranian-backed militants conducted two attacks on US forces stationed at Conoco Mission Support Site and al Omar oil field on December 30. The Islamic Resistance in Iraq—a coalition of Iranian-backed Iraqi militias—conducted two attacks targeting US forces in Iraq and Syria on December 31.
Houthi fighters conducted two attacks on the MV Maersk Hangzhou container ship in the southern Red Sea. The Houthis likely focused on attacking a Maersk-operated vessel in particular because Maersk announced that it would resume its operations in the Red Sea on December 24. These Houthi attacks are part of a broader regional escalation that Iran is leading against the United States and Israel.
Supreme National Security Council Secretary Rear Admiral Ali Akbar Ahmadian discussed the Israel-Hamas war with senior Houthi official Mohammad Abdul Salam in Tehran.
