Iran Update, March 17, 2024

Andie Parry, Annika Ganzeveld, Alexandra Braverman, and Brian Carter

Information Cutoff: 2:00 pm ET

The Iran Update provides insights into Iranian and Iranian-sponsored activities abroad that undermine regional stability and threaten US forces and interests. It also covers events and trends that affect the stability and decision-making of the Iranian regime. The Critical Threats Project (CTP) at the American Enterprise Institute and the Institute for the Study of War (ISW) provides these updates regularly based on regional events. For more on developments in Iran and the region, see our interactive map of Iran and the Middle East.

Note: CTP and ISW have refocused the 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. We do not report in detail on war crimes because these activities are well-covered in Western media and do not directly affect the military operations we are assessing and forecasting. We utterly condemn violations of the laws of armed conflict and the Geneva Conventions and crimes against humanity even though we do not describe them in these reports.

CTP-ISW will publish abbreviated updates on March 16 and 17, 2024. Detailed coverage will resume Monday, March 18, 2024

Key Takeaways:

  • Northern Gaza Strip: The IDF Nahal Brigade (162nd Division) conducted clearing operations in the northern and central Gaza Strip on March 17.
  • West Bank: The IDF arrested seven wanted individuals across the West Bank on March 17. The IDF also confiscated materials needed for manufacturing improvised explosive devices during an operation in Hebron.
  • Northern Israel: Iranian-backed militias, including Lebanese Hezbollah, have conducted at least seven attacks from southern Lebanon into northern Israel since CTP-ISW's last data cutoff on March 16.
  • The Red Sea: The Houthis likely fired at least one unspecified missile targeting the Marshall Islands-flagged LPG tanker MADO in the Gulf of Aden on March 16. This incident marks the second time the Houthis have targeted this vessel in two days.
  • Syria: The Israeli Air Force likely conducted air strikes targeting a Hezbollah ammunitions depot and other Syrian army positions along the Damascus-Homs highway on March 17.


Gaza Strip

Axis of Resistance campaign objectives:

  • Erode the will of the Israeli political establishment and public to launch and sustain a major ground operation into the Gaza Strip
  • Degrade IDF material and morale around the Gaza Strip.|

The Israel Defense Forces (IDF) 162nd Division and combat engineers demolished a 2.5-kilometer-long tunnel in the northern Gaza Strip during the week of March 10.[1] The IDF called the tunnel the “longest underground route” in the northern Gaza Strip that it has discovered during the war. The tunnel network allowed Hamas units to move between the northern and southern Gaza Strip.[2]

The IDF Nahal Brigade (162nd Division) conducted clearing operations in the northern and central Gaza Strip on March 17.[3] The Nahal Brigade killed 18 Palestinian fighters operating near IDF positions using airstrikes, tank fire, and sniper fire.[4] The IDF Nahal Brigade has been operating in the area between the northern and central Gaza Strip for two weeks.[5] The IDF has been constructing a highway in this area, which the IDF has dubbed the “Netzarim corridor.”[6] This corridor divides the northern and southern parts of the Gaza Strip. The Democratic Front for the Liberation of Palestine (DFLP), which is a leftist Palestinian militia aligned with Hamas in the war, mortared Israeli forces at the ”Netzarim site” near the Israeli-built road.[7] Palestinian militias also claimed rocket and small arms attacks near the corridor.[8] Palestinian Islamic Jihad and the al Aqsa Martyrs’ Brigades, which is the self-proclaimed military wing of Fatah and aligned with Hamas in the war, mortared Israeli positions in the eastern part of the Gaza Strip‘s Central governorate in three separate attacks.[9]

Israeli forces continued to conduct clearing operations in Khan Younis on March 17. The IDF said that the IDF Givati Brigade (162nd Division) is still conducting clearing operations in Hamad.[10] The IDF 7th Brigade (36th Division) fought Palestinian fighters and seized weapons in Khan Younis.[11] The al Aqsa Martyrs’ Brigades also engaged Israeli forces operating in Khan Younis.[12]

 

The Popular Front for the Liberation of Palestine (PFLP) mortared Israeli forces at Nahal Oz, which is close to the Israel-Gaza Strip border, on March 17.[13] The PFLP is a secular, leftist Palestinian group fighting alongside Hamas in the war.

Recorded reports of attacks; CTP-ISW cannot independently verify impact.

West Bank

Axis of Resistance campaign objectives:

  • Draw IDF assets and resources toward the West Bank and fix them there

Israeli forces have clashed with Palestinian fighters in at least two locations in the West Bank since CTP-ISW's last data cutoff on March 16.[14]

The IDF arrested seven wanted individuals across the West Bank on March 17.[15] The IDF confiscated materials needed for manufacturing improvised explosive devices during an operation in Hebron.

This map is not an exhaustive depiction of clashes and demonstrations in the West Bank.

Southern Lebanon and Golan Heights

Axis of Resistance campaign objectives:

  • Draw IDF assets and resources toward northern Israel and fix them there
  • Set conditions for successive campaigns into northern Israel

Iranian-backed militias, including Lebanese Hezbollah, have conducted at least seven attacks from southern Lebanon into northern Israel since CTP-ISW's last data cutoff on March 16.[16] The IDF reported that it shot down a “suspicious aerial target” over Acre on March 16.[17] The IDF often uses this language to refer to suspected drones

Recorded reports of attacks; CTP-ISW cannot independently verify impact.

Iran and Axis of Resistance

Axis of Resistance campaign objectives:

  • Demonstrate the capability and willingness of Iran and the Axis of Resistance to escalate against the United States and Israel on multiple fronts
  • Set conditions to fight a regional war on multiple fronts

US Central Command (CENTCOM) reported that US forces destroyed five naval attack drones and one aerial drone in Houthi-controlled areas of Yemen on March 16.[18] CENTCOM assessed that these weapons presented an “imminent threat” to commercial vessels and US Navy ships in the Red Sea.[19] Houthi-controlled and pro-Axis of Resistance media claimed that the United States and the United Kingdom conducted airstrikes in al Durayhimi, Hudaydah governorate and in al Taiziyah, Taiz governorate, on March 16.[20]

CENTCOM also reported that the Houthis launched two drones toward the Red Sea on March 16.[21] CENTCOM intercepted one of the drones. CENTCOM assessed that the second drone likely crashed into the Red Sea.[22] Neither drone caused any casualties aboard or damage to nearby vessels.

The Houthis likely fired at least one unspecified missile targeting the Marshall Islands-flagged tanker MADO in the Gulf of Aden on March 16.[23] UK Maritime Trade Operations reported that an unspecified actor fired at least one missile targeting the MADO. This incident marks the second time the Houthis have targeted this vessel in two days. The UKMTO previously reported that an explosion occurred near the MADO in the Red Sea approximately 65 nautical miles west of Hudaydah on March 15.[24]

The Israeli Air Force likely conducted air strikes targeting a Hezbollah ammunitions depot and other Syrian army positions along the Damascus-Homs highway on March 17.[25] The Syrian Defense Ministry said that the strikes targeted several sites in southern Syria, damaging property and injuring one Syrian soldier.[26] Israeli Army Radio reported that the strikes targeted Syrian army positions and Hezbollah ammunition depots.[27] A Syria-focused analyst noted that the area has a large Hezbollah presence.[28] CTP-ISW has previously reported that the Iranian Islamic Revolutionary Guards Corps (IRGC) may have previously used this highway as a weapons transportation route.[29] The airstrikes caused significant secondary explosions, potentially confirming that the strike targeted an ammunitions
