Iran on Monday said it was continuing talks with mediators from Qatar, Pakistan and Oman in an effort to prevent any further escalation in its war with the United States.
“The role of the mediators is to continue their efforts to prevent an escalation of tensions,” said Iranian foreign ministry spokesman Esmaeil Baqaei.
Addressing a press conference in Tehran, Baqaei said Iran would no longer abide by the memorandum of understanding signed with the United States if Washington failed to uphold its commitments to end the war.
"Each time that the other party has failed to meet its obligations, we did not uphold ours... We will continue to act in this manner," foreign ministry spokesman Esmaeil Baqaei told reporters.
He said Iran has entered “every negotiation with meticulousness and seriousness, keeping in mind the interests and concerns of the Iranian nation”.
“Once an understanding has been reached, it has acted in good faith and seriousness in fulfilling its commitments,” Baqaei said and added “The Islamic Republic of Iran has never been the first to violate its commitments.”
Iran will no longer abide by the memorandum of understanding signed with the United States if Washington fails to uphold its commitments to end the war, he added.
“Each time that the other party has failed to meet its obligations, we did not uphold ours… We will continue to act in this manner,” said Baqaei.
The Foreign Ministry spokesperson says Iran has carried out its pledges under the memorandum of understanding with the United States. “No one can accuse the Islamic Republic of Iran of violating its promises.”
Baqaei said “In all cases our obligations and those of the other party are clear, and it can be proven in a documented manner that the other party has violated various parts of this memorandum of understanding under various pretexts.”
To a question, he said Iran is trying to agree a joint mechanism with Oman for the Strait of Hormuz but US pressure on Oman has hindered efforts.
Iran's Guards strike US military bases in Jordan, Bahrain, Kuwait
Iran's Revolutionary Guards said they had struck US military targets and bases in Jordan, Bahrain and Kuwait after a new round of American attacks across the country, state media reported on Monday.
The official news agency IRNA cited several statements released by the Guards saying they had attacked Prince Hassan Air Base in Jordan, a US military drone command centre in Bahrain and airbases including Ali Al Salem in Kuwait.
The Jordanian military said on Monday it had shot down four Iranian missiles over the country, which Tehran said were intended as retaliation for US strikes.
"At dawn today, air defence systems intercepted and shot down four missiles that had entered Jordanian airspace from Iranian territory," an official source from the Jordanian General Staff said, adding that there were no reports of injuries or damage to property.
Air raid sirens sounded in Bahrain on Monday, the interior ministry said, instructing residents to take shelter following attacks on the island nation as Iran targets US interests in the Gulf.
"The siren has been sounded... citizens and residents are urged to remain calm and head to the nearest safe place," the Ministry of Interior posted on X.
Kuwait's armed forces said they were responding to "hostile aerial targets" on Monday as Iran carries out strikes on US interests in the Gulf.
"The Armed Forces are currently intercepting hostile aerial targets within Kuwaiti airspace," the head of Kuwait's army said in a statement published by the state-run news agency KUNA.
Later, Iran's Revolutionary Guards claimed strikes against Bahrain and Oman, saying they destroyed radar systems in Oman and targeted US military facilities on the southern edge of Manama.
Earlier, the US military said it completed a new round of strikes in Iran aimed at preventing the Islamic republic from attacking shipping in the vital Strait of Hormuz.
"CENTCOM forces struck Iranian military air-defence systems, coastal radar sites, missile and drone capabilities, and small boats using U.S. fighter aircraft, naval vessels, one-way attack aerial drones, and one-way attack sea drones for the first time," the US military said in a post on X.
The flare-up is the latest to undermine an interim agreement between Washington and Tehran aimed at ending their war, which has caused global economic shockwaves since it began in late February.
The latest salvo by US forces began at 2100 GMT on Sunday, Central Command (CENTCOM) said on X, following approximately 140 strikes the previous night.
Iranian state media reported US strikes targeting large areas across southern and western Iran, including Qeshm island and Bandar Abbas near the strait, and in Khuzestan province bordering Iraq.
Iran also reported strikes Sunday evening on two of its southern islands while Kuwait, where Tehran has repeatedly targeted US installations, said border posts and an offshore oil platform had been attacked.
The renewed fighting followed an Iranian attack early Sunday on a commercial ship in the Strait of Hormuz, whose crew was forced to abandon it after it went up in flames.
Iran's Revolutionary Guards said after the incident that "the Strait of Hormuz will be closed until further notice and until the end of American interventions in this region," according to state news agency IRNA.
CENTCOM countered on X that the strait was "open to all vessels seeking to lawfully transit."
The military command added that US forces were "positioned and prepared to ensure" freedom of navigation, saying: "Iran does not control the strait. Traffic is flowing."
Control of the strategic waterway has become key leverage for Iran, with an adviser to the country's supreme leader on Sunday saying it was more important than "dozens of atomic bombs."
Mediators have been trying to salvage a diplomatic solution to ending the war after President Donald Trump this week declared a ceasefire over.
Iran's foreign ministry said the US attacks on Sunday had "caused the return of insecurity in the Strait of Hormuz" and "have rendered futile all efforts" at establishing peace in the region.
- 'Hit them very hard' -
On Sunday evening, Iranian state media reported at least 10 "enemy projectiles" hitting Qeshm Island, which sits on the Strait of Hormuz.
It also reported strikes on the island of Farur, to the east of Qeshm in the Gulf, that it said killed a telecommunications worker and wounded two others.
Official news agency IRNA also reported early on Monday morning that US strikes had killed one person and wounded four at a water pumping station in the southwest city of Mahshahr.
On Sunday, Kuwait said three of its land border posts in the north were damaged in an attack, and that an offshore drilling platform "was targeted by a hostile drone," with one person injured.
Tehran said it had targeted two ships in Hormuz early Sunday, including one that caught fire.
The American military said it had responded with strikes on about 140 targets, and Iranian media reported explosions in Bandar Abbas, Sirik, Jask and on Qeshm, as well as in Khuzestan province, with one soldier reported killed.
Iran's response to the US strikes came quickly, with sirens and explosions heard in Qatar, the United Arab Emirates and Bahrain, AFP journalists and local authorities reported.
Kuwait said it was working to intercept an attack, while Jordan said three Iranian missiles fell inside the kingdom.
Iran's Guards said they also hit Oman, which has rarely been targeted.
Muscat summoned the Iranian ambassador and handed him a formal protest -- a rare move for the sultanate, which has been attempting to balance competing demands from Washington and Tehran.
The attack came just hours after the country hosted Iran's foreign minister to discuss the Strait of Hormuz.
- 'Blatant' attack -
Sunday's attack on a Cyprus-flagged container ship in the waterway left one Indian sailor missing, New Delhi said.
Muscat, meanwhile, said it had rescued 23 crew members from a commercial ship.
The crew abandoned ship and were on a lifeboat, around 17 kilometers (10 miles) east of Oman, British maritime agency UKMTO reported.
Separate Iranian strikes on ships in Hormuz had triggered fighting earlier this week, along with heated rhetoric.
Iran's supreme leader Mojtaba Khamenei has vowed revenge for the killing of his father and predecessor on the first day of the war, and said Iran had compiled a list of individuals to be targeted.
UN Secretary-General Antonio Guterres also called for peace, with his spokesman saying "these attacks must stop."
UN Secretary-General Antonio Guterres urged the United States and Iran Sunday to halt their new outbreak of fighting.
US hit Iran 'very hard': Trump
US President Donald Trump told CNN by telephone on Sunday the two countries had been close to "a deal" on Saturday.
"They were giving up everything, and then all of a sudden two hours after that they hit a ship with a drone. These people, there is something wrong with them," he said.
Oman summons Iranian ambassador
Oman issued a formal protest to the Iranian ambassador following an attack on the country, state media reported -- a rare instance of the sultanate publicly accusing Tehran of targeting its territory.
Oman condemned the "irresponsible acts", a day after hosting the Iranian foreign minister for talks on the Strait of Hormuz.
Hormuz 'more important' than atomic bombs
An adviser to Iran's supreme leader said the Strait of Hormuz was more important than "dozens of atomic bombs".
"This strategic passage is more important than dozens of atomic bombs, and the Islamic Republic of Iran will protect it," Mohsen Rezaee was quoted by the ISNA news agency as saying.
