US President Donald Trump said on Tuesday that 'all hell will rain down' on Iran if they seek to obtain a nuclear weapon, stressing that the agreed peace deal with Tehran specifies they cannot have one.During the G7 summit in France, Trump also said that the US has 'no obligation' to invest in Iran, even after its deal with the Islamic republic to end the Middle East war.'We are not investing any money' in Iran, Trump said after talks with the Emir of Qatar, Sheikh Tamim bin Hamad Al Thani, during a bilateral meeting in France.He also told reporters: 'The only thing that really matters to me is Iran will never have a nuclear weapon, and it says it loud and clear.''All hell will rain down' on Iran if the Iranian government seeks to acquire a nuclear weapon, he added.Trump's comments come after the US President announced this weekend that a deal to end the war with Iran is 'all signed'.The official signing ceremony is set to be held on June 19 in Switzerland.In a post on Truth Social, the president said, 'The deal with the Islamic Republic of Iran is now complete.' In a post on Truth Social, President Donald Trump said: 'The deal with the Islamic Republic of Iran is now complete' Trump discusses the war in the Middle East with the Emir of Qatar, Sheikh Tamim bin Hamad Al Thani, at a bilateral meeting in France'I hereby fully authorise the toll-free opening of the Strait of Hormuz, and, simultaneously herewith, authorise the immediate removal of the United States Naval blockade,' he added.Meanwhile, Israeli politicians quickly condemned the deal, and Prime Minister Benjamin Netanyahu pledged that the country's forces would remain in Gaza, Lebanon and Syria 'for as long as necessary'.Trump said Tuesday he had suggested to Israel that Syrian President Ahmed al-Sharaa should deal with Lebanon's Tehran-backed Hezbollah militia as the Israeli campaign was causing too many casualties.Praising Sharaa as doing an 'amazing job', Trump said: 'If Israel can't do the job [against Hezbollah] without killing everyone else, then he [Sharaa] will do the job. Syria will do the job.'Sharaa 'is very good with Hezbollah, does not like them', Trump said, adding that the Syrian leader, an ex-jihadist who came to power after the fall of Bashar al-Assad, is 'no boy scout'.Israel 'is fighting Hezbollah too long and too many people are being killed,' he said.'I suggested to Israel to let Syria take care of Hezbollah as, to be honest with you, I think they would do a better job,' said Trump.Following reports that his relationship with Israeli Prime Minister Benjamin Netanyahu was in decline, Trump said 'Bibi [Netanyahu] has to be more responsible with respect to Lebanon'.'I am not happy with the way Israel had handled themselves with Lebanon and Hezbollah. They should have been able to do the job faster,' Trump said.Asked at the G7 when the text of the deal would be released, Trump said: 'It's a very powerful document, and I want it to be released. So probably pretty soon.'Iran said Tuesday that talks with the United States on its nuclear programme and sanctions relief would likely begin later this week, as Trump said the Strait of Hormuz would 'completely open' once the foes sign their deal.Officials say negotiations over a final deal would take place in a 60-day window after the memorandum of understanding to end nearly four months of war triggered by US-Israeli strikes on Iran is physically signed. The rubble of destroyed buildings in Deir Qanoun al-Nahr, Tyre district, southern Lebanon'Likely on Friday, at a location to be determined... a new round of negotiations between Iran and the United States to reach a final agreement will begin,' Iranian Foreign Minister Abbas Araghchi said.'In the final agreement, decisions will be made on the nuclear issues and the lifting of sanctions.'According to Iran's deputy foreign minister, Mohammad Bagher Ghalibaf, the Islamic republic's top negotiator, will attend the signing in Switzerland.The US side will be represented by Vice President JD Vance, who said Trump himself might also attend.The developments came after Trump said an Iranian blockade on the crucial Hormuz Strait oil and gas route would be fully lifted by the same day, which would be a major boost to the global economy.The US had, in retaliation, imposed its own blockade on Iranian ports.'Ships are starting to move, many loaded up with oil, out of the Strait of Hormuz,' Trump said Monday, adding later that he did not 'think we will need much help' keeping the waterway open.Iran's military hailed the accord as a victory, claiming it had 'humiliated' the US and Israel, while President Masoud Pezeshkian called it 'a great achievement' for the region.The ultra-conservative newspaper Vatan-e Emrooz praised the agreement as a 'Trump surrender document'.But Araghchi struck a more cautious note, saying: 'We have a history of broken commitments... we have a history of agreements being torn up. All of this is present in our minds.'A senior US administration official, however, said Trump, Vance and negotiator Ghalibaf had already signed the text electronically.In a flurry of interviews to talk up the deal, Vance said no US taxpayer money would go to Iran under the deal, as Iranian media reported $12 billion of frozen assets would be released.

'I've known President Trump for a long time. I would say that means go back and resume bombing. It could. It could be, and he would. I don't think he would hesitate,' said Vance.Trump arrived in the spa resort of Evian-les-Bains for the summit, hosted by French President Emmanuel Macron, flush from celebrating his 80th birthday watching UFC cage fighting at the White House the previous night. The Strait of Hormuz will be 'completely open' from Friday after demining is completed, Trump said at the start of bilateral talks with Macron ahead of the summit opening.But to Macron's apparent surprise he also said: 'I don't think we are going to need much help' on keeping the Strait open, after London and Paris proposed a joint naval mission.Macron had said earlier France and UK were 'ready to act very quickly' on the Hormuz mission.
