Iran Update Special Report, April 26, 2026

The Institute for the Study of War (ISW) and The Critical Threats Project (CTP) at the American Enterprise Institute are publishing daily updates to provide analysis on the war with Iran. The updates focus on US and Israeli strikes on Iran and Iran and the Axis of Resistance’s response to the strikes. The updates cover events from the past 24-hour period.

Key Takeaways

Toplines

Prospects for meaningful US-Iran negotiations remain low due to the Islamic Revolutionary Guards Corps’ (IRGC) domination of decision-making and opposition to compromise. Iranian Foreign Affairs Minister Abbas Araghchi travelled to Muscat, Oman, on April 26 to discuss security in the Strait of Hormuz with Omani Sultan Haitham al Tariq.[1] Araghchi then travelled to Islamabad, Pakistan, to discuss Iran’s preconditions for talks with the United States with Pakistani mediators, including the end of the US blockade on Iranian ports.[2] IRGC-affiliated media reported on April 26 that Araghchi discussed the implementation of ”a ⁠new legal regime over the Strait of Hormuz,” war compensation, and a guarantee of no future US attacks.[3] There was no reported discussion of Iran’s nuclear program, which is a key issue for the United States. US President Donald Trump said that Iran sent the United States a “much better” offer 10 minutes after he canceled US Special Envoy to the Middle East Steve Witkoff and Jared Kushner’s planned trip to Islamabad, Pakistan, for talks with Iran on April 25.[4] Trump said the new offer involves Iran not having a nuclear weapon but added that it is “not enough.”[5]

Israel deployed an Iron Dome battery and Israeli Defense Forces (IDF) personnel to the United Arab Emirates (UAE), which demonstrates the deepening of Israeli and Emirati security ties as a result of the war. Two Israeli officials and one US official told Western media on April 26 that Israeli Prime Minister Benjamin Netanyahu ordered the IDF to send an Iron Dome battery and “several dozen” IDF personnel to operate it after a phone call with Emirati President Mohammed bin Zayed.[6] Unspecified Israeli and Emirati officials also told Western media that both countries have been “coordinating closely military and politically” since the start of the war.[7] Israel and the UAE have been expanding their defense cooperation since the UAE normalized its relations with Israel by signing the Abraham Accords in 2020.[8]

Maritime Developments

The United States has continued to enforce its blockade on Iranian ports. US forces intercepted the US-sanctioned, Panamanian-flagged Sevan (IMO: 9177806) gas tanker on April 25 in the Arabian Sea.[9] The US Treasury Department sanctioned the Sevan on April 24 for transporting Iranian oil and gas products to foreign markets.[10] The Sevan entered the Strait of Hormuz on April 21 via the Iranian-approved route and crossed the US blockade line on April 24, according to commercially available shipping data. Maritime intelligence company Tanker Trackers said on April 25 that the Sevan recently loaded gas in Iran, and travels frequently to Bangladesh and Yemen.[11] US Central Command (CENTCOM) stated on April 25 that it has redirected 37 Iranian or Iranian-linked vessels since the start of the blockade.[12]

US-Israeli Air Campaign

Nothing significant to report.

Iranian Response

Six people familiar with the matter told NBC News that an Iranian F-5 fighter jet caused some damage to Camp Beuhring, which is a major US base in Kuwait, within the “first few days” of the war.[13] Iran conducted multiple attacks targeting the base at the start of the war.[14]

Israeli Campaign Against Hezbollah and Hezbollah Response

The IDF struck Lebanese Hezbollah infrastructure, fighters, and launchers across southern Lebanon on April 25 and 26.[15] Israeli Prime Minister Benjamin Netanyahu said that the IDF was operating with “significant force” after Hezbollah attacks on Israeli forces in Lebanon.[16] The IDF issued evacuation orders for seven Lebanese villages immediately north of the Litani River on April 26.[17] The IDF warned residents that Hezbollah violated the ceasefire.[18] The IDF said that it struck Hezbollah infrastructure and a rocket launcher.[19] Lebanese media reported Israeli strikes on targets in at least 16 villages and towns in southern Lebanon on April 26.[20]

Hezbollah launched drones targeting Israeli forces in southern Lebanon, framing its attacks as a “legitimate response” to alleged Israeli ceasefire violations. Netanyahu accused Hezbollah of “effectively eroding the ceasefire” through its continued attacks.[21] Hezbollah framed its attacks targeting Israeli towns and Israeli troops in southern Lebanon as a “legitimate response” to continued Israeli airstrikes and operations in Lebanon.[22] Hezbollah continued to fire drones targeting Israeli troops in southern Lebanon, including first-person view (FPV) drones. A Hezbollah FPV drone struck near an IDF tank in Taybeh, southeastern Lebanon, and killed a soldier from the 1st (Golani) Infantry Brigade (36th Armored Division).[23] Hezbollah also fired two other FPV drones targeting Israeli forces evacuating casualties.[24] The IDF also intercepted two unspecified Hezbollah drones in southern Lebanon.[25]

Hezbollah published footage of a fiber-optic FPV drone attack targeting an Israeli tank in Mays al Jabal on April 11.[26] Hezbollah has “increasingly” used both FPV and fiber optic FPV drones to target Israeli troops in southern Lebanon since the IDF first entered Lebanon in March 2026.[27] Fiber-optic FPV drones are immune to jamming.[28]

Hezbollah also continued to fire munitions targeting northern Israel. The IDF intercepted three Hezbollah drones that triggered alerts over the Western Galilee on April 26.[29] Hezbollah has not claimed the attack as of this writing. CTP-ISW assessed on April 26 that Hezbollah may be conducting smaller-scale attacks targeting uninhabited areas of northern Israel and Israeli forces in southern Lebanon to demonstrate that it can threaten Israeli security and will respond to Israeli operations in Lebanon without provoking a large Israeli response.[30]

Hezbollah harshly criticized the Lebanese government for not securing an Israeli commitment to end operations in southern Lebanon during recent Israel-Lebanon talks in Washington, DC.[31] Hezbollah called the Lebanese government “impotent“ and accused it of “emboldening” Israel’s ability to “violate” the ceasefire.[32] Hezbollah’s criticism of the Lebanese government, which it used to justify its “right“ to attack Israel, is part of the group’s long-standing narrative about the necessity of its own role in defending Lebanon.

Other Axis of Resistance Response

Nothing significant to report.
