Israeli forces are operating in Khan Younis as part of the Israel Defense Force (IDF)’s effort to target senior Hamas commanders. Israeli Prime Minister Benjamin Netanyahu said on December 6 that the Israeli military had encircled Hamas leader in the Gaza Strip Yahya Sinwar’s house in Khan Younis. Residents in the area told Reuters that Israeli tanks neared his home. IDF spokesperson Rear Admiral Daniel Hagari said that Sinwar is likely underground in Hamas’ extensive tunnel network. Israel has claimed repeatedly that senior political and military Hamas leadership, including Sinwar and Hamas’ military chief Mohammed Deif, are hiding in Khan Younis.

Palestinian militia fighters continued to use more sophisticated tactics to target Israeli forces throughout the Gaza Strip on December 5. This is consistent with the tactical shift CTP-ISW has observed since the end of the humanitarian pause. The al Qassem Brigades—the militant wing of Hamas—claimed that its fighters detonated a house-borne improvised explosive device (HBIED) targeting Israeli forces east of Khan Younis on December 5. The HBIED collapsed the building. The group claimed that it detonated multiple claymore-type, anti-personnel mines in an ambush east of Khan Younis on December 5. The al Qassem Brigades also targeted an Israeli tank with an EFP north of Khan Younis on December 4. Al Qassem Brigades fighters inside an Israeli cantonment filmed Israeli soldiers relaxing inside the position near Juhor ad Dik. The group claimed that they filled a tunnel under the cantonment with explosives and detonated it "among 60 Israeli soldiers.”

Israel continued to conduct clearing operations in the northern Gaza Strip to encircle Hamas in Shujaiya neighborhood and Jabalia city. Israeli Defense Minister Yoav Gallant observed Israeli forces in Shujaiya and Jabalia on December 4 and noted that the forces have returned there to “close the circle.” The Wall Street Journal reported that the Israel Defense Forces (IDF) have cornered Hamas fighters in the last two strongholds in the northern Gaza Strip. An IDF spokesperson issued a warning to Hamas commanders in Shujaiya that they are targets and that Israel will use extreme force in the neighborhood to dismantle Hamas military infrastructure on December 3.

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.

The IDF Arabic-language spokesperson released on X (Twitter) at 0222 ET on December 2 specific evacuation orders covering Jabalia, Gaza city, and eastern Rafah and Khan Younis governorates. The orders highlight specific blocks and neighborhoods in these areas. The evacuation notices called for civilians to go to “known shelters.”

Fighting resumed in the Gaza Strip after negotiations between Israel and Hamas broke down. The Israel Defense Forces (IDF) reported one hour before the truce was set to end that it intercepted an aerial object fired from the Gaza Strip into Israel

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.

Israeli officials and international mediators expect that the humanitarian pause with Hamas will be extended. The current pause in fighting between Israel and Hamas lasts until November 30. An anonymous senior Israeli official told the Washington Post that Israel expects the pause to continue for another two to three days after November 30. The Qatari Foreign Ministry spokesperson told CNN on November 29 that they are “very optimistic” that an extension will be announced in the coming hours. The New York Times reported that top officials from Qatar, Egypt, Israel, and the United States are discussing extending the pause to allow for further hostages/prisoner exchanges. Anonymous senior Egyptian officials told the Wall Street Journal that Hamas leaders said that Hamas would agree to an additional four-day extension of the truce, according to Egyptian and Qatari mediators.

Israel and Hamas both reported at least one violation of the temporary truce agreement in the Gaza Strip on November 28, but neither side escalated the situation to more general fighting across the strip. Both parties claimed that the other bore responsibility for the violations. Neither side indicated an intention to resume hostilities as a result of the violations, however. Israeli Army Radio reported that Palestinian fighters detonated three improvised explosive devices (IED) targeting Israeli forces in two separate attacks. Palestinian fighters detonated two remotely detonated IEDs targeting IDF soldiers boarding armored vehicles near Rantisi Hospital, which is along the agreed truce line, in one attack. Palestinian fighters also detonated one IED and fired small arms at Israeli forces in an unspecified location, according to Israeli Army Radio. Israel said the two attacks “slightly” wounded five Israeli soldiers. Hamas’ military spokesperson said that there was “field friction” in the northern Gaza Strip that was part of a “clear violation by [the IDF] of the truce agreement.” The spokesperson said Hamas remains committed to the pause in fighting.

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.
