Tensions over potential widespread fighting in the area eased on Monday after both countries reported an end to military operations in response to a presidential appeal for peace. In a televised address, the prime minister stated that hostilities with Iran had paused following retaliatory action, and warned that any renewed aggression would be met with a forceful response, noting that attacks ceased after strikes on Tehran's government.

The Houthi movement in Yemen, which maintains ties with Iran, launched attacks toward Israel and indicated that vessels associated with Israel in the Red Sea would be considered targets, raising regional tensions. Observers note that any renewed truce remains tenuous, with numerous potential triggers for resumed hostilities and rocket exchanges.

Officials in Israel have turned down multiple attempts by Iran to make any permanent halt in hostilities conditional on ending operations in Lebanon targeting Hezbollah, an organisation with strong connections to Tehran. Israel's defence minister stated on Monday that operations against Hezbollah in Lebanon would persist, with potential strikes on Beirut should the group attack Israel, and noted that Iranian efforts to coordinate actions between Lebanon and Iran would face substantial military response similar to recent actions, according to Israel Katz.

Sunday's missile launches from Iran followed Israeli strikes on Hezbollah-controlled areas in Beirut's southern districts. Iran continued to maintain its position. On Monday, Iran's parliamentary speaker and chief negotiator indicated that Tehran would not accept what it described as ongoing breaches, stating on social media that without authentic commitment to establishing confidence, the country's position would stay unchanged.

Trump has urged Israel to halt military operations in Lebanon to facilitate negotiations aimed at resolving the broader conflict with Iran, including a phone conversation with Netanyahu last week that featured strong language. The prime minister confronts an upcoming election and domestic calls to maintain operations limiting Hezbollah's capacity for strikes.

Reports emerged Monday of rocket fire from Hezbollah, which receives Iranian support, targeting northern Israel, and an Israeli strike occurred near Tyre in southern Lebanon. A petrochemical facility in Iran was targeted during recent operations conducted by Israeli forces. According to military statements, air defence installations positioned throughout Iran were targeted and destroyed during the operation. Explosions were heard across several cities including Isfahan, Karaj, Tabriz and Tehran, according to broadcasts from the country.

Military officials in Iran stated they had carried out strikes against Israel in response to actions in Lebanon, including operations near Beirut on Sunday. The Revolutionary Guard announced it had struck two Israeli military installations. Debris from a missile originating in Iran damaged multiple residences in a settlement located in the West Bank, with no casualties recorded.

The escalation in hostilities affected financial markets, with oil prices rising 5% and raising the possibility of increased fuel costs globally. Equity markets gained value as the parties reportedly reached a temporary pause in their retaliatory actions.

The escalating hostilities have further hindered efforts to conclude the conflict, which began on 28 February when airstrikes conducted jointly resulted in the death of Ayatollah Ali Khamenei, who had held the position of supreme leader. Although the ceasefire established two months ago ended major hostilities, sporadic clashes continue in maritime areas of the Gulf.

On Monday, Trump wrote on social media that Israel and Iran were both pursuing a ceasefire without delay. He stated that discussions on the agreement were advancing, though obstacles remained, and confirmed the blockade of Iranian ports would continue pending completion of the arrangement.

A foreign ministry spokesperson stated that the nation was communicating with Washington amid considerable distrust. He stated that Israel's operations in Lebanon, whether conducted with or without US approval and coordination, were designed to undermine diplomatic efforts, noting that few accept the notion that Israel would undertake such measures without advance consultation and collaboration with the United States.

The conflict interrupted peace negotiations that had been underway. Iran stated that the conflict might broaden, with potential consequences for global economic stability.

In a statement, the armed group from Yemen with connections to Iran announced intentions to disrupt Israeli shipping routes through the Red Sea and reported launching projectiles toward Israel over recent days. Until now, the group has maintained minimal involvement in the broader conflict. Their oversight of the Red Sea entrance has become increasingly important as a bypass for substantial daily volumes of Middle Eastern petroleum, particularly since restrictions on maritime traffic through the Strait of Hormuz have limited access for most vessels.

Iran's national emergency organisation reported that the most recent strikes attributed to Israel resulted in injuries to 15 individuals, with 14 of those occurring in Mahshahr county, though fatalities were not recorded. Emergency medical services confirmed that the rocket strikes toward Israel caused no casualties.

In March, Israeli forces entered Lebanon following border fire from Hezbollah, which acted in support of Tehran at the war's outset. Israeli strikes have resulted in fatalities exceeding 3,500 in Lebanon, while casualties from Hezbollah operations include at least 29 soldiers and three civilians in Israel.

The negotiating position put forward includes a cessation of hostilities in Lebanon, removal of forces, release of approximately half the frozen overseas funds, and a measure of control over the Strait of Hormuz, a waterway that previously handled one-fifth of global crude oil and liquefied natural gas shipments. Officials indicated that postponement of specific conversations regarding verification mechanisms—including potential down-blending of enriched uranium reserves—remained under consideration.

Negotiators from Iran have faced domestic opposition from a limited yet outspoken faction of conservative legislators who advocate withdrawing from the discussions entirely. Some observers argue that certain elements of the agreement lack clarity and require further refinement.

According to Danny Orbach, a military historian at Hebrew University, the strikes conveyed that any final agreement with Iran must account for the country's security concerns, as it retains the capacity to disrupt negotiations that overlook its strategic priorities.
