Israel and Iran exchanged airstrikes, as Iran's military rejected President Donald Trump's claim the US was in negotiations to end to the war which has roiled energy and financial markets, saying the US is negotiating with itself.
The rejection of negotiations by the unified command of the Iranian Armed Forces, which is dominated by the hardline elite Revolutionary Guards, comes amid reports the US has sent a 15 point plan for discussion to Tehran.
"Has the level of your inner struggle reached the stage of you (Trump) negotiating with yourself?" the top spokesperson for Iran's joint military command, Ebrahim Zolfaqari, said on Iranian state TV.
"People like us can never get along with people like you."
"As we have always said... no one like us will make a deal with you. Not now. Not ever."
Iran's leadership has previously said it can not negotiate with the US as it has attacked the country twice during high level negotiations in the past two years.
Four weeks into the war that has killed thousands, created the worst energy shock in history and sparked global inflation fears, there was no let up in airstrikes from Iran and Israel.
The Israeli Defence Forces said in a Telegram post it had launched a wave of strikes targeting infrastructure across Tehran. The semi-official Iranian SNN News Agency said the strikes hit a residential area in the city, with rescuers searching the rubble.
Kuwait and Saudi Arabia said they had repelled fresh drone attacks, without stating where they originated.
Drones targeted a fuel tank at Kuwait International Airport, causing a fire but no casualties, Kuwait's Civil Aviation Authority said.
Iran's Revolutionary Guards said it had launched a new wave of attacks against locations in Israel including Tel Aviv and Kiryat Shmona, as well as US bases in Kuwait, Jordan and Bahrain, Iranian state media reported.
Mr Trump told reporters at the White House yesterday that the US was in "negotiations" with "the right people" in Iran to end the war, adding the Iranians wanted to reach a deal very badly.
Stocks rose and oil prices fell on reports the US is seeking a month-long ceasefire and had sent a 15-point plan to Iran for discussion, raising hopes for a resumption of oil exports out of the Persian Gulf.
The New York Times reported that the US sent Iran a 15-point plan to end the war in the Middle East.
Israel's Channel 12, quoting three sources, said the US was seeking a month-long ceasefire to discuss the 15-point plan.
A source familiar with the matter confirmed that the US had sent a plan to Iran but provided no further details.
The Israeli media outlet said the plan would include the dismantling of Iran's nuclear programme, ceasing support for proxy groups, such as Lebanon's Hezbollah, and the reopening of the Strait of Hormuz.
The US and Israel launched strikes on Iran on 28 February after saying they had failed to make enough headway in talks aimed at ending Iran's nuclear programme, although mediator Oman said significant progress had been made.
The US struck Iran's nuclear facilities in June 2025.
Since the start of "Operation Epic Fury" by the US last month, Iran has attacked countries that host US bases, struck Gulf energy infrastructure and effectively closed the Strait of Hormuz, conduit for a fifth of the world's oil and liquefied natural gas.
Iran has told the United Nations Security Council and the International Maritime Organization that "non-hostile vessels "may transit the Strait of Hormuz if they coordinate with Iranian authorities", according to a note seen by Reuters.
The effective closure of the waterway, where 20% of the world's oil and gas normally transits, has created the worst energy supply shock in history, sent fuel prices soaring, and disrupted global aviation.
Asia is at the frontline of the fuel crisis, buying more than 80% of the crude that transits the Strait of Hormuz, and governments there are scrambling to respond to fuel shortages with policies such as enforced work-from-home and stimulus measures enforced during the Covid pandemic.
Some countries have declared public holidays and closed schools.
The International Energy Agency has agreed to a record release of around 400 million barrels of oil from strategic stockpiles to deal with the crisis, and Japanese Prime Minister Sanae Takaichi asked IEA chief Fatih Birol for an additional release of oil when they met, Jiji Press reported.
Pakistan's Prime Minister Shehbaz Sharif said he was willing to host talks between the US and Iran on ending the war.
Pakistan has long-standing ties to neighbouring Iran's Islamic Republic and has been building a relationship with Mr Trump.
Despite reports of negotiations, the Pentagon is expected to send thousands of soldiers from the US Army's elite 82nd Airborne Division to the Middle East, two people familiar with the matter told Reuters on Tuesday, adding to a massive US military buildup.
The forces will add to the 50,000 U.S. troops already in the region and accelerate Washington's massive US military buildup there, fuelling fears of a longer conflict.
