Iran–Israel proxy conflict in the context of April 2024 Iranian strikes on Israel

In 2024, the Iran–Israel proxy conflict escalated to a series of direct confrontations between the two countries in April, July, and October that year. On 1 April, Israel bombed an Iranian consulate complex in Damascus, Syria, killing multiple senior Iranian officials. In response, Iran and its Axis of Resistance allies seized the Israeli-linked ship MSC Aries and launched strikes inside Israel on 13 April. Israel then carried out retaliatory strikes in Iran and Syria on 19 April.

On 31 July, Hamas political leader Ismail Haniyeh was assassinated, in Tehran, Iran. The killing of Haniyeh occurred a few hours after the 2024 Haret Hreik airstrike in Lebanon that assassinated Hezbollah commander Fuad Shukr.

On 13 April 2024, the Islamic Revolutionary Guards Corps (IRGC), a branch of the Iranian Armed Forces, in collaboration with the Islamic Resistance in Iraq, Lebanese militant group Hezbollah, and the Ansar Allah (Houthis), launched attacks against Israel and the Israeli-occupied Golan Heights with loitering munitions, cruise missiles, and ballistic missiles. The attack was codenamed by Iran as Operation True Promise (Persian: وعده صادق, romanized: va'de-ye sādeq). Iran said it was retaliation for the Israeli bombing of the Iranian embassy in Damascus on 1 April, which killed two Iranian generals. The strike was seen as a spillover of the Gaza war and marked Iran's first direct attack on Israel since the start of their proxy conflict.

Several countries in the Middle East closed their airspace a few hours before Iran launched a standoff attack against Israel around midnight on 13 April. Iran's attack sent around 170 drones, over 30 cruise missiles, and more than 120 ballistic missiles toward Israel and the Israeli-occupied Golan Heights. The Israel Defense Forces used Arrow 3 and David's Sling systems to shoot down many of the incoming weapons. American, British, French, and Jordanian air forces also shot some down. France, which intervened at Jordan's request, deployed warships to provide radar coverage. Jordan said it had intercepted objects flying into its airspace to protect its citizens.

The background to the Iran–Israel war (13–24 June 2025) focuses on historical events during their proxy conflict since 1985, including scrutiny of Iran's nuclear program in the 1980s and 1990s, Iran signing the Joint Comprehensive Plan of Action (JCPOA) in 2015, and US President Donald Trump suspending US participation in the deal in 2018. In the past, Israel has fought wars with Iranian proxies including against Hezbollah since the 1982 Lebanon War.

In 2015, six countries negotiated the JCPOA nuclear deal to lift sanctions on Iran and freeze Iran's nuclear program. In 2018, US president Trump unilaterally withdrew from and voided the JCPOA, after which Iran began stockpiling enriched uranium, and the International Atomic Energy Agency (IAEA) lost the ability to monitor Iran's nuclear facilities.

Hezbollah involvement in the Syrian civil war has been substantial since the beginning of armed insurgency phase of the Syrian civil war in 2011, and evolved into active support for Syrian government forces and troop deployment from 2012 onwards. By 2014, Hezbollah was deployed across Syria. Hezbollah has also been very active in preventing Al-Nusra Front and Islamic State penetration into Lebanon, being one of the most active forces in the Syrian civil war spillover in Lebanon. Hezbollah's involvement in Syria came to an end with the fall of the Assad regime as a result of a renewed rebel offensive in late 2024, leading to clashes between Hezbollah and the new Syrian transitional government.

In the past, Hezbollah has served a strategic arm of Iran in the region, playing a key role in the Iran–Israel and Iran–Saudi Arabia proxy conflicts. On a number of occasions, Hezbollah weapon convoys in Syria and Syrian-Lebanese border areas were attacked, presumably by the Israeli military. Hezbollah convoys and militant camps have also been attacked by various Syrian rebel factions.
