Iran has issued a stark warning to former President Donald Trump, cautioning that an invasion would plunge American forces into a “swamp of death.” The warning comes amid heightened tensions in the region.

Iranian leaders declared that their military forces are prepared to confront U.S. troops, threatening to “set them on fire” and vowing retribution against America’s regional allies.

Recently, approximately 2,500 U.S. Marines were deployed to the Gulf, fueling speculation about President Trump’s possible plans for a ground offensive in the area.

Mohammad-Bagher Ghalibaf, the speaker of Iran’s parliament, accused the United States of contemplating a ground attack under the guise of seeking diplomatic resolution. This accusation follows the arrival of the USS Tripoli, an amphibious assault ship, in the Middle East on Friday, bringing thousands of marines and sailors.

Ghalibaf emphasized, “Our firing continues. Our missiles are in place. Our determination and faith have increased.”

Meanwhile, U.S. officials informed the Washington Post that any ground operation would likely be limited in scope, potentially consisting of targeted raids rather than a full-scale invasion.

But Islamic Revolutionary Guard Corps spokesman Ebrahim Zolfaqari said yesterday: ‘Unfortunately, the leaders of the United States have delegated the authority to command the armed forces to someone who, due to imbalance, dangerous and wrong positions and decisions, has led the US army into the swamp of death.’

US Central Command said the USS Tripoli was equipped with ‘transport and strike fighter aircraft, as well as amphibious assault and tactical assets’.

American military leaders have discussed seizing Kharg Island, a key Iranian oil export hub in the Persian Gulf, as well as raiding coastal areas near the blockaded Strait of Hormuz, the Washington Post reported.

Troops may be deployed to destroy weapons that could target commercial and military shipping, officials said, with one adding that the objectives might take ‘a couple of months’.

However, US Secretary of State Marco Rubio said on Friday that America could achieve all its objectives without ground troops.

The war, which has now entered its fifth week, has threatened global supplies of oil and gas, caused a shortage of fertiliser, and severely disrupted air travel.

Iran’s grip on the Strait of Hormuz and its retaliatory attacks on Gulf states have sent shockwaves through global markets.

In the past month, 13 US troops have been killed in action.

Some 62 per cent of Americans are opposed to a ground invasion, according to an Associated Press poll, with 12 per cent in favour.

Seizing Kharg Island would be hazardous, and it might be safer for forces to lay mines around the island to compel Iran to remove its own devices laid in the Strait of Hormuz, a military expert said.

Retired Army officer Michael Eisenstadt, a director at the Washington Institute for Near East Policy, said: ‘I just wouldn’t want to be in that small place with Iran’s ability to rain down drones and maybe artillery.’

Meanwhile, Britain is preparing to deploy a Royal Navy ship that has been retro-fitted with autonomous mine-hunting drones, the Sunday Times reported.

The amphibious landing vessel RFA Lyme Bay could be sent to the Strait of Hormuz. A defence source said no decision had been taken, but added: ‘This preventative step gives ministers options… to help resume the normal flow of merchant shipping.’

Mr Trump has criticised Britain, claiming the UK ‘should be involved enthusiastically’ with efforts to reopen the waterway.

Iran’s blockade of the strait has sent global fuel prices soaring, with a barrel of crude oil hitting as much as £85 – up from about £50 before the war.

Mr Trump said on Saturday that negotiations with Tehran were ‘going very well’, even though Iran insists it is not negotiating with the White House.

He had warned Iran to end the blockade – which has left about 2,000 vessels trapped in the Persian Gulf – or face strikes on its energy infrastructure, but has extended the deadline to April 6.

It came as Pakistan announced last night that it would host talks between the US and Iran in days.

Electricity was cut in parts of the Iranian capital Tehran and the nearby city of Karaj yesterday after attacks on infrastructure, with shrapnel taking part of the electricity grid offline.
