Israeli forces continued clearing operations in Khan Younis as Palestinian militias attempt to resist Israeli advances. Israeli forces located several tunnel shafts and a Hamas military headquarters as they advanced in Khan Younis. The Israel Defense Forces (IDF) engaged three Palestinian fighters as they emerged from a tunnel in central Khan Younis and fired a rocket-propelled grenade (RPG).Hamas maintains an extensive tunnel system across the Gaza Strip, which Israeli forces have destroyed as they have advanced. Israeli forces also raided a mosque from which Hamas fighters were operating. The IDF said the Hamas fighters detonated an IED near Israeli forces.

Iranian-backed Iraqi actors are exploiting the Israel-Hamas war to try to expel US forces from Iraq. Forcing the removal of the US military is one of Iran’s most important strategic objectives in the Middle East. CTP-ISW previously assessed that the dozens of Iranian-backed militia attacks on US military positions in recent weeks have been meant to impose a cost on the United States for supporting Israel while also eroding American willingness to remain militarily in Iraq and Syria. Iranian and Axis of Resistance leaders are operating on the theory that relatively low levels of militant pressure gradually diminish the willingness of the US political establishment to sustain deployments in the Middle East.

Hamas has used increasingly sophisticated tactics against Israeli forces in the Gaza Strip since the humanitarian pause ended on December 1. Hamas and other Palestinian militias have used explosively formed penetrators (EFP) five times since December 1. These attacks mark a noteworthy increase in the use of EFPs in the Israel-Hamas war. Hamas claimed that it used EFPs only twice prior to December 1, and Palestinian Islamic Jihad (PIJ) claimed no EFP attacks prior to December 2. Hamas separately conducted a complex ambush targeting Israeli forces northeast of Khan Younis on December 3 (see below). Hamas also released a video on December 2 showing its force launching three one-way attack drones targeting Israeli forces in the northern Gaza Strip. The Israel Defense Forces (IDF) have not confirmed that Hamas is employing these systems or tactics against its forces.

Members of the Israeli policy community have expressed concerns in recent days that Iran’s so-called “Axis of Resistance” has built the capability to attack Israel from the West Bank and Lebanon in addition to the Gaza Strip. An Israeli think tank published an article on November 29 describing the risk of a Lebanese Hezbollah (LH) ground attack into northern Israel in a way similar to Hamas’ October 7 attack. The article stated that LH “poses a significant challenge for the IDF and still poses a clear and present danger.” Mark Regev—a senior adviser to the Israeli prime minister—similarly warned on November 30 that Hamas seeks to attack Israeli targets inside and from the West Bank. Regev expressed concern that Hamas could conduct an escalation from the West Bank into Israel similar to Hamas’ October 7 attack. CTP-ISW has reported extensively on how Iran has invested in building military capabilities and infrastructure in the West Bank in recent months.

Hamas and Israel completed the fourth swap of Hamas-held hostages for Israeli-held prisoners on November 27 in accordance with their humanitarian pause agreement. Hamas released 11 Israeli hostages.Israel is set to release three women and 30 others, including minors, in exchange. Palestinian media sources, including Hamas-affiliated outlets, reported that Israel released some of the prisoners at the time of writing. The parties had delayed the exchange briefly, as Israel and Hamas disagreed on which hostages Hamas would release. Hamas had sent a list of hostages to be released to Israel on November 26 that Israel renegotiated on November 27, causing the delay.

Israel and Hamas have agreed to a four-day humanitarian pause in fighting. Hamas official Mousa Abu Marzouk said the pause will begin at 0300 EST on Thursday, November 23. The Israeli National Security Director said that hostages will not be released before Friday, however.It is therefore unclear when the pause will begin. Statements from Israel and Hamas acknowledged a prisoner/hostage swap in return for a four-day pause in the fighting in the Gaza Strip with different levels of detail. The Israeli government’s official statement said that 50 women and children would be released by Hamas over four days at a rate of at least 10 per day. Hamas’ political wing issued a more detailed statement and said that it would release 50 Israeli women and children under the age of 19 in exchange for Israel releasing 150 Palestinian women and children under the age of 19. Israel’s statement presents the opportunity for the extension of the pause, stipulating that for each additional 10 hostages Hamas released, a day would be added to the pause. Hamas’ statement did not mention this aspect of the agreement.

Israeli forces continued reconnaissance operations in al Shifa Hospital on November 16 to uncover Hamas military infrastructure, according to the Israel Defense Forces (IDF). US military doctrine defines reconnaissance as “a mission undertaken to obtain, by visual observation or other detection methods, information about the activities and resources of an enemy or adversary or to secure data concerning the. . . geographic characteristics of a particular area.” Reconnaissance operations can occur before, during, or after an operation. The IDF will probably not release the intelligence that the reconnaissance generates immediately because the intelligence is meant to enable further military operations to clear, destroy, or otherwise degrade the tunnel system that the IDF claims Hamas maintains under al Shifa Hospital. An IDF spokesperson said that Israeli special forces are conducting unidentified targeted operations against Hamas infrastructure around the complex, which this intelligence could enable.

Israel is pressuring Hamas to surrender its position inside the al Shifa Hospital. Hamas prevented al Shifa Hospital staff from accepting fuel from Israeli forces, according to the Israel Defense Forces. Israeli forces advanced further into the al Nasr neighborhood in the northwestern Gaza Strip. Israeli forces also fought with Palestinian militia fighters at the al Quds Hospital in southwestern Gaza City. The IDF said it has weakened 10 out of 24 Hamas battalions in the Gaza Strip.

Israeli ground forces advanced along the northwestern Gazan coast amid reports of clashes with Hamas in the area. IDF spokesman Rear Admiral Daniel Hagari said Israeli ground forces have fully encircled Gaza City and split the whole Gaza Strip into two. The al Qassem Brigades—the militant wing of Hamas—released footage of its militants operating in or around the al Shati Refugee Camp. Independent analyst on X (Twitter) geolocated the footage to the Ahmed Oraby road north of the al Shati camp. The footage shows militants launching rocket propelled grenades (RPGs) at IDF tanks. Both the al Quds Brigades—the militant wing of the Palestinian Islamic Jihad (PIJ)—and the Al Aqsa Martyrs’ Brigade said they targeted Israeli vehicles in northwestern Gaza on November 5.

Hamas and its allies are preparing the information environment to blame Israel for the possible deaths of hostages in the Gaza Strip, especially if Hamas begins killing hostages. Hamas military spokesperson Abu Ubaida said on October 9 that Hamas would kill hostages in response to Israeli airstrikes, indicating Hamas’ willingness to do so for perceived military and/or political gains. Tasnim News Agency—an Iranian outlet affiliated with the Islamic Revolutionary Guard Corps (IRGC)—reported on October 22 that Israel’s “clandestine goal” is to “cause the killing of captive Israelis,” according to “informed sources. Palestinian Islamic Jihad (PIJ) spokesperson Abu Hamza said on October 24 that Israel does not “pay attention” to the lives of hostages.
