Since the Iranian Revolution in 1979, the Islamic Republic of Iran has been embroiled in tense relations with the U.S. and its allies. Following the hostage crisis, both countries severed relations. Since then, both countries have been involved in numerous direct confrontations, diplomatic incidents, and proxy wars throughout the Middle East, which has caused the tense nature of the relationship between the two to be called an 'international crisis'. Both countries have often accused each other of breaking international law on several occasions. The U.S. has often accused Iran of sponsoring terrorism and of illegally maintaining a nuclear program, as well as using strong rhetoric against Israel, of which Iran has questioned its legitimacy and its right to exist while supporting Hamas, an antizionist terrorist group in the Gaza Strip. Meanwhile, Iran has often accused the U.S. of human rights violations and of meddling in their affairs, especially within the Iranian Democracy Movement.
Kata'ib Hezbollah or the Hezbollah Brigades, is a radical Iraqi Shiite paramilitary group which is a part of the Iraqi Popular Mobilization Forces (PMF), staffing the 45th, 46th, and 47th Brigades. During the Iraq War (2003–11), the group fought against Coalition forces. It has been active in the War in Iraq (2013–2017) and the Syrian civil war (2011–present). The group was commanded by Abu Mahdi al-Muhandis until he was killed in a US drone attack in 2020. Thereafter, he was replaced by Abdul Aziz al-Muhammadawi, as the new leader of the PMF. KH seeks to establish an Iran-aligned government in Iraq, expel American forces from the country, and advance the regional and international interests of Iran in Iraq and the region. The group is responsible for killing hundreds of U.S. soldiers and takes a central part in carrying out attacks against U.S. targets in Iraq and acts as part of the Axis of Resistance. Kata'ib Hezbollah has received extensive training, funding, logistic support, weapons, and intelligence from the Quds Force of Iran's Islamic Revolutionary Guard Corps (IRGC).
The History of the Israel Air Force begins in May 1948, shortly after the formation of the State of Israel. Following Israel's declaration of independence on May 14, its pre-state national institutions transformed into the agencies of a state, and on May 26, 1948, the Israeli Air Force was formed. Beginning with a small collection of light aircraft, the force soon transformed into a comprehensive fighting force. It has since participated in several wars and numerous engagements, becoming what has been described as "The mightiest air force in the Middle East".
The May 2013 Rif Dimashq airstrikes were a series of aerial attacks made on targets in Syria on 3 and 5 May 2013. The 3 May attack was on targets at Damascus International Airport. The 5 May attacks were on targets at Jamraya, and the Al-Dimas and Maysalun areas in Rif Dimashq. Although officially Israel neither confirmed nor denied its involvement, former Mossad director Danny Yatom and former government member Tzachi Hanegbi inferred Israel's involvement in the attack. Official Syrian sources denied any attack on its soil on 3 May, but did accuse Israel for the attacks on 5 May.
Several incidents have taken place on the Israeli–Syrian ceasefire line during the Syrian Civil War, straining the relations between the countries. The incidents are considered a spillover of the Quneitra Governorate clashes since 2012 and later incidents between Syrian Army and the rebels, ongoing on the Syrian-controlled side of the Golan and the Golan Neutral Zone and the Hezbollah involvement in the Syrian Civil War. Through the incidents, which began in late 2012, as of mid-2014, one Israeli civilian was killed and at least 4 soldiers wounded; on the Syrian-controlled side, it is estimated that at least ten soldiers were killed, as well as two unidentified militants, who were identified near Ein Zivan on Golan Heights.

The Iran–Israel conflict during the Syrian civil war refers to the Iranian–Israeli standoff in and around Syria during the Syrian conflict. With increasing Iranian involvement in Syria from 2011 onwards, the conflict shifted from a proxy war into a direct confrontation by early 2018.
The 2019 Israeli airstrikes in Iraq began as unidentified drone or aircraft bombings of the Iranian-backed Popular Mobilization Forces (PMF) bases in Iraq starting on 19 July 2019. The strikes targeted Iranian proxy groups, based in Iraq, as well as IRGC operatives.
On 29 December 2019, the United States conducted airstrikes against Kata'ib Hezbollah's weapons depots and command centers in Iraq and Syria, reportedly killing at least 25 militiamen and wounding 55 more. The U.S. Department of Defense said the operation was in retaliation for repeated attacks on Iraqi military bases hosting Operation Inherent Resolve (OIR) coalition forces, particularly the 27 December 2019 attack on a Kirkuk airbase that left an American civilian contractor dead. Kata'ib Hezbollah, an extremist Shi'ite militia funded by Iran, denied any responsibility for the attacks.
On February 25, 2021, the United States military carried out an airstrike on a site which it believed to have been occupied by Iranian-backed Iraqi militias operating from across the border in eastern Syria. The unilateral operation was in retaliation for multiple rocket attacks against U.S. forces in Iraq ten days prior and was the first known offensive military operation carried out under U.S. president Joe Biden.
On 28 June 2021, President Biden directed airstrikes against Iran-backed militia groups close to the Syria-Iraq border. F-15E and F-16 aircraft were used to launch the attack in what the U.S. described as a retaliatory attack against U.S. facilities and personnel in Iraq by militia groups. Two operational and weapons storage facilities were targeted in Syria, the U.S. military revealed in a statement. Despite the U.S. not disclosing the information regarding the casualties in the attack, the SOHR stated that at least nine Iran-backed Iraqi militia fighters died, leaving many others injured. Iraqi militia groups aligned with Iran in a statement named four members of the Kataib Sayyed al-Shuhada faction they said were killed in the attack on the Syria-Iraq border.

Events in the year 2023 in Syria
Starting on 17 October 2023, and in response to United States support for Israel in the Israel–Hamas war, Iran-backed militias initiated a coordinated series of more than 170 attacks on U.S. military bases and assets in Syria, Iraq, and Jordan. These attacks resulted in injuries to dozens of U.S. service members. In retaliation, the U.S. has launched multiple counterattacks, resulting in the death of over 30 militants including a senior commander of the Nujaba Movement, Mushtaq Talib al-Saidi. In February 2024, following U.S. airstrikes in Iraq and Syria, militia attacks against U.S. forces were halted.

The following is a timeline of the Syrian civil war for 2024. Information about aggregated casualty counts is found in Casualties of the Syrian civil war.
Since the beginning of the Israel–Hamas war, which has mostly been confined to southern Israel and the Gaza Strip, a number of armed clashes and standoffs have been reported in other parts of the Middle East, particularly involving Shia Islamist militias backed by Iran. There has been speculation that any escalation of these incidents, specifically between Israel and Hezbollah—an Iranian-backed Shia militia which is based in southern Lebanon and which is more powerful than the Lebanese Armed Forces —could bring the entire region into a full-scale military conflict. In addition to the Israel–Hezbollah conflict, the Iranian-backed Houthi militia—which controls parts of northern Yemen, but is not internationally recognized as the country's government —became directly involved in the conflict by firing missiles at Israeli cities, albeit on a limited scale; the Houthis have since focused more on seizing civilian cargo ships passing through the Red Sea in order to inflict economic losses on Israel and the global economy, evoking American and British airstrikes against Houthi-controlled Yemen. Iranian-backed militias in Iraq and Syria have also mounted numerous attacks against American military bases in the region; these confrontations have increasingly escalated tensions between long-time adversaries Iran and the United States, especially after the 2024 Iranian missile strikes in Iraq and Syria. In the West Bank, over 100 Palestinians have been killed in armed confrontations with Israeli soldiers and Israeli settlers, as violence in the territory increased drastically following the Hamas-led attack on Israel.
On 2 February 2024, the United States Air Force launched a series of airstrikes targeting Iran's Revolutionary Guards and Iran-backed militia groups located in Iraq and Syria. The attack was launched in retaliation against a drone strike carried out by the Islamic Resistance in Iraq targeting US troops in Jordan the week before, which killed three U.S. troops.
