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.
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.”
Russia likely deployed elements of at least two Central Military District (CMD) brigades to reinforce offensive operations by Donetsk People’s Republic (DNR) forces on the Avdiivka front. A Ukrainian military observer reported on October 16 that three Russian brigades — the DNR’s 114th Motorized Rifle Brigade (MRB) and the CMD’s 15th and 21st MRBs (both of the 2nd Combined Arms Army [2nd CAA]) — have been involved in recent attacks on Avdiivka alongside various scattered DNR elements, while Russian forces are holding the CMD’s 30th MRB in tactical reserve. Elements of the CMD, particularly of the 2nd CAA, have been active along the Svatove-Kreminna line until recently, and the newly formed 25th CAA likely relieved them along the Svatove-Kreminna line. 2nd CAA elements have primarily conducted defensive operations along the Svatove-Kreminna line for the last several months and have therefore likely had more time to rest and reconstitute before deploying to a more challenging sector of the frontline, which accounts in part for recent Russian advances in the previously stagnant Avdiivka sector of the front.
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.
Russian President Vladimir Putin may be trying to temper expectations of significant Russian advances around Avdiivka in Donetsk Oblast. Putin claimed in an interview on Russian state television on October 15 that Russian forces are conducting an “active defense” in the Avdiivka, Kupyansk, and Zaporizhia directions. Putin’s characterization of Russian offensive operations near Avdiivka as an “active defense,” instead of “active combat operations” as Russian UN Ambassador Vasily Nebenzya claimed on October 13, or discussing Russian operations as an “offensive” as some milbloggers have, may be an attempt to temper expectations of significant Russian advances. Russian operations including intensive artillery and airstrikes are likely intended to degrade Ukrainian forces around Avdiivka. Russian forces are unlikely to make significant breakthroughs or cut off Ukrainian forces in the settlement in the near term, and potential advances at scale would likely require a significant and protracted commitment of personnel and materiel.
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.
US and Ukrainian officials reported on October 12 and 13 that they anticipated the Russian offensive operations around Avdiivka and expressed confidence in Ukrainian defenses. US National Security Council Spokesperson John Kirby reported on October 13 that the new Russian offensive operations near Lyman and Avdiivka “did not come as a surprise.” Kirby stated that the US is confident that Ukrainian forces will repel these Russian attacks. Kirby also reported that Russian forces appear to be using human wave tactics, wherein the Russian military uses masses of poorly trained and equipped Russian soldiers to attempt to advance - the same practice Russian forces used during their failed winter offensive in winter 2023. ISW has additionally observed Russian forces using higher than usual numbers of armored vehicles in ongoing operations. Ukrainian Main Military Intelligence Directorate (GUR) Representative Andriy Yusov similarly reported on October 12 that Ukrainian forces knew about and prepared for the Russian attack near Avdiivka and that Russian forces did not form sufficient reserves to attack along the entire frontline, but only in certain sectors. Several Russian milbloggers claimed that Ukrainian mines are slowing Russian advances near Avdiivka, indicating Ukrainian prior preparations for the attack.
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.
Ongoing Russian offensive operations throughout the Avdiivka, Donetsk Oblast area on October 13 reportedly faced setbacks around the city. Russian sources claimed that Russian forces continued to attack areas north and south of Avdiivka, and geolocated footage published on October 12 and 13 indicates that Russian forces advanced south of Krasnohorivka (5km north of Avdiivka) and southeast of Pervomaiske (11km southwest of Avdiivka). Russian sources also published conflicting reports about previous claims by Russian sources of Russian control of the Avdiivka Coke Plant, and ISW has not observed any evidence to confirm that Russian forces control the plant as of publication. Ukrainian military officials reported that Ukrainian forces continue to repel Russian attacks around Avdiivka.[3] A Russian milblogger noted that Ukrainian forces are using minefields to slow down Russian advances in the Avdiivka direction. A Russian volunteer in the 4th Luhansk People’s Republic (LNR) Brigade (2nd Army Corps, Southern Military District) claimed that worn out barrels are reducing the accuracy of Russian artillery near Avdiivka, a complaint about Russian artillery that ISW has previously observed from Russian sources.The volunteer assessed that Russian forces can ”compress the [Ukrainian] perimeter” by capturing less fortified Ukrainian-held territory near Avdiivka, but expressed concern that Russian generals will misinterpret these limited advances and try to speed up offensive efforts towards Avdiivka. The volunteer noted that such a misinterpretation may lead Russian forces to “beat on concrete” fortifications until these forces run out.
Turkey began an air incursion against the US-backed Syrian Democratic Forces (SDF) on October 1, which will likely impede the SDF’s ability to execute operations against ISIS. Iranian and Iranian-backed forces are deploying to the Israeli-Syrian border, which may enable ISIS to embed itself in the population in Deir ez Zor and conduct attacks to incite sectarian tension in Damascus. ISIS will likely take advantage of the changing Iranian and SDF priorities to accelerate ISIS’s campaigns of isolating regime and SDF units to prepare to build support among the population.
