Israel–Hamas War (Iran Updates)

This page collects the refocused Iran Updates that ISW and The Critical Threats Project (CTP) at the American Enterprise Institute began publishing on October 7, 2023. ISW and CTP refocused the Iran Update to cover the Israel–Hamas war. The new sections address developments in the Gaza Strip, the West Bank, Lebanon, and Syria, as well as noteworthy activity from Iran’s Axis of Resistance.

Iran Update, October 16, 2023

Iranian Foreign Affairs Minister Hossein Amir Abdollahian warned on October 15 and 16 that a multi-front war against Israel is becoming more likely and that Iranian-backed militias may take preemptive actions against Israel in the “coming hours.” Abdollahian stated in an interview with Al Jazeera on October 15 that Israel’s continued siege of Gaza is making a multi-front war “increasingly more probable.” Abdollahian similarly posted on X (Twitter) on October 16 that “the time for political solutions is coming to an end” and that the expansion of the Israel-Hamas war to new fronts is becoming “inevitable.”

Iran Update, October 15, 2023

Palestinian militias continued drone and indirect fire attacks into Israel, primarily southern Israel. CTP-ISW did not record any reports of infiltrations or small arms clashes in southern Israel.
The rate of small arms clashes between Israeli forces and Palestinian militants has continued to fall after peaking on October 13.
Lebanese Hezbollah expanded its campaign against Israeli forces along the Israel-Lebanon border in terms of pace, location, and actors involved. The IDF spokesperson stated that Iran has instructed LH to escalate against Israel and thereby impose pressure on the IDF while it prepares for ground operations into the Gaza Strip.
The IDF conducted an airstrike on the Aleppo International Airport, marking the second time that the IDF has struck this location since the war began on October 7.
Iran and elements of its Axis of Resistance are messaging that the Hamas-Israel war could expand geographically into a multi-front conflict. CTP-ISW is closely monitoring the situation to forecast whether such a scenario is becoming more or less likely.
Iranian Foreign Affairs Minister Abdollahian met with senior Hamas and Qatari officials during an official visit to Doha.

Iran Update, October 14, 2023

Hamas continued its ground and rocket attacks into Israel, primarily southern Israel, on October 14. The al Qassem Brigades—Hamas’ militant wing—claimed responsibility for conducting rocket attacks on 12 locations, including Tel Aviv. Saraya al Quds—the militant wing of Palestinian Islamic Jihad (PIJ)—claimed responsibility for launching rockets on seven locations in southern Israel. Hamas has reduced its rate of rocket fire into Israeli territory since October 12 to conserve its stockpile and prepare for a prolonged war.

Iran Update, October 13, 2023

Hamas continued conducting rocket attacks into Israel at a lower rate of fire on October 13 compared to previous days. Hamas began reducing its rate of attacks on October 12 to conserve its rocket stockpile and prepare for a prolonged war, as CTP and ISW previously reported. Hamas targeted northern, central, and southern Israel on October 13. Hamas’ military spokesman announced that the group fired 150 rockets at Ashkelon, 50 rockets at Sderot, and bombed the Ben Gurion Airport in central Israel. Israeli civilians have evacuated the periphery areas of Gaza. Hamas’ al Qassem Brigades claimed that the rocket barrages are in response to Israel’s displacement and targeting of civilians. The IDF’s operational update on October 13 notes that militants have launched 6,000 rockets from Gaza. CTP-ISW previously reported that Hamas and the Palestinian Islamic Jihad (PIJ) have expended around 33 percent of their rocket arsenal since the war began.

Iran Update, October 12, 2023

Hamas continued rocket attacks from the Gaza Strip into southern Israel but reduced the rate of these attacks on October 13. An IDF commander stated that Hamas is trying to conserve its rocket stockpile and prepare for a prolonged war. Israel estimates that Hamas and Palestinian Islamic Jihad (PIJ) have expended around 33 percent of their rocket arsenal since the war began on October 7.

Iran Update, October 11, 2023

Hamas incursions into southern Israel by land and sea have slowed since October 9. Palestinian militant groups are now relying on rocket barrages and attack drones to hit towns in northern and southern Israel. Rocket fire from Gaza extended north to Haifa and multiple barrages have hit Tel Aviv. The Hamas spokesperson warned Israeli civilians to evacuate Ashkelon near the Gaza border before the group launched hundreds of rockets on October 10, claiming the attack was retribution for Israeli airstrikes on Gaza. Hamas warnings have not preceded such rocket barrages previously. Israel conducted strikes in over 1,270 locations in Gaza and killed at least three Hamas leaders over the two-day period. The Israel Defense Forces (IDF) spokesperson stated early on October 10 that its forces regained control of the Gaza border. Clashes continued in isolated pockets immediately north and east of the Gaza Strip on October 10 and 11, however.

Iran Update, October 9, 2023

Hamas is expanding its incursions into southern Israel as Palestinian militias in the West Bank and Lebanese Hezbollah (LH) clash with Israeli security forces in the northern province of the country. The situation could expand the war to a second front. Hamas launched a surprise ground and air attack into Israel on October 7 which included sending hundreds of fighters into Israel to attack nearby border posts, military sites, and residential areas. Israel is conducting airstrikes in Gaza to retaliate. Iran’s Axis of Resistance is aligning itself with Hamas’ operation, however.

Iran Update, October 8, 2023

Palestinian militias in Gaza responded to calls from Hamas to join in fighting against Israeli security forces on October 8. Lebanese Hezbollah (LH) and Palestinian militias also conducted attacks on Israeli positions from south Lebanon and the West Bank, respectively, which could expand the war to a second front.
