Shin Bet announced on March 25 that the IDF seized a “significant amount of advanced arms from Iran” that Iran had smuggled into the West Bank to support Palestinian militia attacks targeting Israel. The captured arms included 83 small arms, five anti-tank mines, four grenade launchers, 15 RPGs, and 25 kilograms of plastic explosives. Shin Bet also said that a Fatah official based in Lebanon and affiliated with Lebanese Hezbollah and the IRGC assisted the Iranian effort to smuggle arms into the West Bank, but Shin Bet did not provide further details. Shin Bet added that the Iranian Islamic Revolutionary Guards Corps (IRGC) Quds Force organized the effort to smuggle Iranian weapons into the West Bank, which is consistent with previous Western reporting.

The Israel Defense Forces (IDF) concluded a weeklong operation in and around al Shifa Hospital on March 23. Israeli forces engaged Palestinian fighters during a raid targeting an unspecified “wanted individual” in Tulkarm in the West Bank on March 22. Lebanese Hezbollah has conducted at least eight attacks from southern Lebanon into northern Israel since CTP-ISW's last data cutoff on March 22. CENTCOM reported that the Houthis launched four anti-ship ballistic missiles into the Red Sea but added that the Houthi attacks did not damage any military or commercial vessels.

The Israel Defense Forces (IDF) continued to conduct an operation in and around al Shifa Hospital in Gaza City on March 22. The IDF 401st and Nahal Brigades (162nd Division) and Israeli special operations forces have killed approximately 150 Palestinian fighters in the hospital area since the operation began on March 18.

Israeli forces continued to conduct an operation in and around al Shifa Hospital in Gaza City on March 21. Israeli special operations forces and the Israel Defense Forces (IDF) 401st Brigade (162nd Division) killed approximately 50 Palestinian fighters and located ammunition depots near the hospital over the last 24 hours. IDF spokesperson Daniel Hagari stated on March 21 that Palestinian fighters remain barricaded in the al Shifa Hospital emergency room and that the Israeli forces are focused on evacuating civilians from the area before clearing the full hospital.

Kataib Hezbollah Secretary General Abu Hussein al Hamidawi said during a meeting with unspecified leaders in Iran’s so-called “Axis of Resistance” in Tehran on March 20 that the current pause in attacks on US forces does not mark the end of efforts to expel US forces from Iraq.

Iran is likely concerned that Armenia’s deteriorating relations with Russia and outreach to the West could increase NATO’s presence along its northern border. Iranian President Ebrahim Raisi discussed the security situation in the Caucasus with Russian President Vladimir Putin in a phone call on March 19. Raisi told Putin that Iran is “ready to maintain stability” and protect Iran’s strategic interests in the Caucasus. Iran’s interests in the Caucasus include keeping overland trade routes open, preventing Israel from using Azerbaijan’s territory to operate against Iran, and preempting the spread of separatist sentiments among Iran’s Azeri minority. Russian readouts of Raisi and Putin’s phone call notably did not mention that the pair discussed the Caucasus.

The Popular Mobilization Forces (PMF) is an Iraqi state security service that Iran has infiltrated and uses to wield significant influence in Iraq. Iran’s cooptation of the PMF enables Tehran to pursue its objectives in Iraq while obfuscating its actual involvement in Iraqi internal affairs. Understanding how Iranian leaders wield direct and indirect influence over this significant component of the Iraqi security sector is crucial as the United States considers how to deter Iranian-backed Iraqi militias from attacking US forces in Iraq and Syria.

Israeli forces conducted a "high-precision operation" at al Shifa Hospital on March 18 based on intelligence that Hamas was using it for militant activity. The Israel Defense Forces (IDF) reported that they had intelligence that senior Hamas officials were using the area to conduct and direct attacks in the Gaza Strip. Israeli ground forces advanced to the hospital with bulldozers and tanks and detained more than 200 Palestinians. Palestinian militias, including Hamas, engaged Israeli forces around al Shifa Hospital during the operation.

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. 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.

Israeli Prime Minister Benjamin Netanyahu approved plans on March 15 for a military operation into Rafah. The Prime Minister’s Office did not provide additional details. US Secretary of State Antony Blinken told reporters that the Biden administration has not seen the plan and the Biden administration does not know how Israel plans to protect civilians in Rafah. The IDF said on March 13 that it plans to move civilians from Rafah to “humanitarian enclaves” in the central Gaza Strip before any Israeli offensive into Rafah. There are approximately 1.4 million displaced Palestinian civilians currently in Rafah.
