Iran suspends military action against Israel amid warning over Lebanon strikes

Iran has reportedly halted military operations against Israel after U.S. President Donald Trump held separate discussions with leaders in both Tel Aviv and Tehran, urging them to exercise “restraint” and avoid any further escalation in the already volatile Middle East situation. The development has raised hopes of a temporary de-escalation after months of heightened military exchanges that got renewed Monday morning and had intensified concerns over a broader regional conflict and disruptions to global energy supplies.

However, tensions in the region remain elevated as Tehran warned that any continuation of Israeli strikes on Lebanon would invite harsher retaliation. Iranian authorities maintained that while military operations had been paused following diplomatic outreach from Washington, the country remained prepared to respond aggressively to what it described as “provocative actions” by Tel Aviv. The warning has kept geopolitical risks alive, with market participants closely monitoring further developments across the region.

Strikes before ‘restraint’
In a major escalation of the over three-month-long Middle East conflict, Israeli forces on Monday struck a key petrochemical plant in south-western Iran, along with several other military installations, despite US President Donald Trump reportedly urging restraint against fresh attacks. The strikes by the Israel Defense Forces (IDF) came in retaliation after Iran’s Islamic Revolutionary Guard Corps (IRGC) targeted two military bases in Israel earlier in the day and warned of further attacks on non-military and energy infrastructure.

The targeted site, known as the Mahshahr petrochemical complex, is located in Iran’s south-western Khuzestan province and is among the country’s largest petrochemical production hubs. In a post on Telegram, the IDF said on Monday, without disclosing specific operational details, “The Israeli Air Force has attacked several targets at the petrochemical complex in Mahshahr in southwest Iran.” Reports indicated that the strikes damaged parts of Karoon Petrochemical Company’s facilities in Mahshahr. Karoon operates a 40,000-tonnes-per-annum methylene diphenyl diisocyanate (MDI) plant and an equal-capacity toluene di-isocyanate (TDI) plant at the site.

Separate reports suggested that chlorine-related units and storage facilities were also damaged during the Israeli strikes in Khuzestan province on Monday. Any prolonged disruption could affect both domestic supply chains and exports from one of Iran’s most important petrochemical hubs. Karoon is located in Mahshahr, which hosts a concentration of petrochemical facilities that form a major pillar of Iran’s non-oil economy.

Significance of Karoon
Karoon Petrochemical Company is one of Iran’s leading petrochemical producers and the first manufacturer of isocyanates in the Middle East. Located in the Bandar Imam Petrochemical Special Economic Zone in Khuzestan province, the company specialises in the production of toluene diisocyanate (TDI) and methylene diphenyl diisocyanate (MDI), which are widely used in the manufacture of polyurethane foams, insulation materials, automotive components, coatings and industrial adhesives.

The company has an annual production capacity of around 80,000 tonnes of isocyanates, comprising 40,000 tonnes each of TDI and MDI, along with significant by-products such as hydrochloric acid and bleach. Karoon plays a strategic role in supplying raw materials to Iran’s downstream chemical and manufacturing industries while also catering to export markets across Asia and Europe. The United States imposed sanctions on PGPIC and dozens of its affiliated companies in 2019, alleging that the group generated billions of dollars in revenue that helped finance the Islamic Revolutionary Guards Corps (IRGC) and its engineering and construction arm, Khatam al-Anbiya.

According to the US Treasury Department, several PGPIC subsidiaries maintained business links with Khatam al-Anbiya through engineering, construction and financing contracts valued at hundreds of millions of dollars. Washington has repeatedly stated that Iran’s petrochemical sector serves as a major source of funding for the IRGC’s military and strategic activities. The IRGC has long retained a strong presence across Iran’s energy and industrial sectors through an extensive network of companies, contractors and affiliated entities involved in large-scale infrastructure projects and export-oriented businesses.

Israel’s reaction
Israeli military officials reiterated on Monday that one of the key objectives of recent strikes was to damage infrastructure used in the manufacture of raw materials considered essential for ballistic missile production. They argued that disrupting such supply chains could weaken Iran’s ability to sustain and expand its missile programme.

Petrochemical facilities are primarily civilian industrial enterprises, although several of their products can also serve strategic military purposes. Chemical compounds produced at Iran’s major petrochemical hubs, including Mahshahr and Assaluyeh, are widely used in commercial manufacturing but may also function as precursor materials in the production of missile propellants and other defence-related components.

Israel has previously alleged that certain industrial sites in the Mahshahr region were involved in the production of materials linked to Iran’s missile programme. During earlier military operations targeting industrial infrastructure in the area, Israeli officials claimed that some facilities were supporting Tehran’s ballistic missile capabilities through the supply of critical chemical inputs.

The petrochemical sector’s dual-use nature has long remained a point of international concern, as facilities designed to support civilian industries can also produce materials with potential military applications. This overlap has increasingly placed strategic industrial sites at the centre of geopolitical tensions in the region.

Iran’s action
IRGC accused Israel of escalating tensions in the region by targeting civilian infrastructure and energy facilities, warning that such actions could trigger wider repercussions across the Middle East’s energy sector. Meanwhile, Tehran has launched a fresh wave of strikes targeting Israeli air bases, describing the attacks as retaliation for Israeli military operations in Lebanon and subsequent strikes carried out inside Iran. The renewed exchange of hostilities has heightened concerns over the possibility of a broader regional conflict involving key energy-producing nations.

“By taking action against civilian targets and targeting oil industries, the Zionist enemy has started a dangerous game, the scope of which will encompass all energy targets in the region,” the IRGC said in a statement. It further warned that any disruption to regional energy infrastructure could have serious consequences for the global economy, placing responsibility on what it described as the “main arsonist in this field — the United States.”

The latest escalation comes despite repeated calls by US President Donald Trump for restraint and reports that Washington had attempted to dissuade Israeli Prime Minister Benjamin Netanyahu from pursuing further retaliatory measures. According to Reuters, the strike on Mahshahr marked the first known attack on an Iranian energy facility since the April ceasefire, raising fears of a wider regional confrontation and potential disruption to ongoing US-Iran diplomatic negotiations.
