Iran’s Revolutionary Guards said on Wednesday that a return to war with the United States was unlikely, but warned the Islamic republic stood ready to respond to any attack.

The statement came a day after Iran accused the US of breaching the ceasefire in place since April, and warned it was prepared to retaliate following the most serious strikes since the truce took effect.

In Lebanon, where a truce has done little to halt the violence in Israel’s war with Hezbollah, Israeli strikes killed 31 people on Tuesday, according to the Lebanese health ministry.

The Middle East war erupted in late February with US-Israeli strikes on Iran, spreading swiftly across multiple fronts and engulfing the region, while throwing global energy markets into chaos.

Mohammad Akbarzadeh, deputy political chief of the Islamic Revolutionary Guard Corps Navy, said that while the likelihood of returning to war is low because of the enemy’s weakness, the armed forces are lying in wait with full magazines.

He went on to warn that the military would turn the area along Iran’s coastline into a graveyard for aggressors, in quotes carried by the Tasnim news agency.

Tehran’s intelligence ministry said the US and Israel were still seeking to overthrow the Islamic republic and partition Iran.

The ministry said it had evidence that they would smuggle various weapons, ammunition and illegal communication tools, especially Starlink satellite internet devices, into Iran to foment religious and ethnic divisions and carry out sabotage missions.

Oil prices drop

Iran and the US have for weeks been engaged in a war of words as they try to negotiate a deal, with mediation efforts led by Pakistan.

With no clear winner in the war, neither side appears ready to compromise on the key sticking points, which include the Strait of Hormuz and Iran’s nuclear programme.

Iran blockaded the strait, which is vital to global energy flows, in retaliation for the war, while the US responded with a counter-blockade of Iranian ports.

On Wednesday, the Revolutionary Guards’ navy insisted that only ships willing to abide by Iranian order would be allowed to pass through the waterway.

US Secretary of State Marco Rubio said on Tuesday that a peace deal remained within reach, but that the Strait of Hormuz would be reopened one way or the other.

Oil prices, which are still well above pre-war levels, fell on Wednesday on rekindled hopes for progress in the US-Iran talks, with international benchmark Brent North Sea crude dropping 5% to $94.61 a barrel.

Iranians fear renewed conflict

The Iranian authorities partially restored access to the global internet on Tuesday, after a three-month shutdown.

Hana (20), a student in Tehran who gave only her first name, said: “I do feel better now because I finally can use my favourite applications. At the same time, I have this concern that war might resume any minute and just cut me off again from my friends.”

Amir (27), a software developer in the Iranian capital, also said he feared renewed fighting.

“I feel like nothing is certain yet, even though the ceasefire is still ongoing and there is news of a possible agreement. But the daily question is, will there be missile strikes tonight?” he said.

There have been flare-ups during the ceasefire, with the most recent coming overnight Monday to Tuesday, when the US military said it launched self-defence strikes, while providing few details. Iran’s foreign ministry accused Washington of a gross violation of the ceasefire.

In a statement marking the start of the Eid al-Adha holiday, Tehran’s supreme leader Ayatollah Mojtaba Khamenei declared Washington was losing its influence in the Middle East and warned countries in the region to stop hosting bases from which the US could launch attacks.

The United States, he said in a written statement, in addition to no longer having any safe haven in the region for aggression and the establishment of military bases, is moving further and further away from its former position with each passing day.

Dozens dead in Lebanon

In southern Lebanon, Israel carried out strikes on Tuesday that Beirut’s health ministry said killed 31 people, including at least four children.

An AFP correspondent at one strike site near the city of Tyre saw rescue workers removing debris on Wednesday and carrying a white body bag from the rubble, which was strewn with household items like rugs and cushions.

Iran has demanded that any peace accord apply to Lebanon, where a 17 April truce has failed to stop fighting that began when militant group Hezbollah attacked Israel in early March.

Israeli Prime Minister Benjamin Netanyahu on Monday vowed to crush Hezbollah, and an Israeli military official told AFP the following day that the country’s forces were expanding their ground operations deeper inside Lebanon.

Hezbollah said its fighters clashed with Israeli forces at point-blank range on Wednesday in a strategically significant town north of the Litani River, just beyond an Israeli-declared yellow line in south Lebanon where its troops have been operating.
