The Pentagon is preparing for weeks of limited ground operations in Iran, potentially including raids on Kharg Island and coastal sites near the Strait of Hormuz, according to United States officials quoted by The Washington Post newspaper.

The plans, which fall short of a full invasion, could involve raids by special operations and conventional infantry troops, the Post reported on Saturday, exposing US personnel to Iranian drones and missiles, ground fire, and improvised explosives.

Whether President Donald Trump would approve any of those plans remains uncertain, according to the report.

“It’s the job of the Pentagon to make preparations in order to give the Commander in Chief maximum optionality. It does not mean the president has made a decision,” White House press secretary Karoline Leavitt said in a statement, responding to questions over the Post report.

The Trump administration has deployed US Marines to the Middle East as the war in Iran stretches into its fifth week, and has also been planning to send thousands of soldiers from the army’s 82nd Airborne to the region.

On Saturday, the US Central Command (CENTCOM) said about 3,500 additional soldiers arrived in the Middle East on board the USS Tripoli.

The sailors and marines are with the 31st Marine Expeditionary Unit and arrived in the region on March 27, along with “transport and strike fighter aircraft, as well as amphibious assault and tactical assets”, according to CENTCOM.

Officials speaking to The Washington Post said discussions within the administration over the past month have touched upon the possible seizure of Kharg Island, a key Iranian oil export hub in the Gulf, and raids into other coastal areas near the Strait of Hormuz to find and destroy weapons that can target commercial and military shipping.

According to the report, one person said the objectives under consideration would probably take “weeks, not months” to complete, while another put the potential timeline at “a couple of months”.

The Pentagon had not responded on Saturday to the Post’s requests for comment. Iran has yet to respond to the report.

The report comes as Pakistan, which shares a 900km-long (559-mile) border with Iran, mediates between Washington ‌and Tehran, hosting two days of talks starting on Sunday with the foreign ministers of Saudi Arabia, Turkiye and Egypt.

The Iranian parliament speaker, Mohammad Bagher Ghalibaf, said on Sunday the “enemy openly sends messages of negotiation and dialogue and secretly plans a ground attack”.

“Unaware that our men are waiting for the arrival of American soldiers on the ground to set fire to them and punish their regional partners forever. Our firing continues. Our missiles are in place,” the Tasnim news agency reported, quoting Ghalibaf.

“Our determination and faith have increased. We are aware of the enemy’s weaknesses, and we clearly see the effects of fear and terror in the enemy’s army.”

It was not clear whether Ghalibaf was responding to the Post report.

On Wednesday, Ghalibaf had warned that intelligence reports suggested that “Iran’s enemies” ⁠were planning to occupy an Iranian island with support ‌from an unnamed country in the region.

He said any such attempt would be met with targeted attacks on the “vital infrastructure” of the regional country – which he did not name – that assists in the operation.

Meanwhile, Iran’s navy chief Shahram Irani said on Sunday that the USS Abraham Lincoln aircraft carrier would be targeted if it comes within range.

“As soon as the USS Abraham Lincoln carrier strike group comes within firing range, we will avenge the blood of the martyrs of the Dena warship by launching various types of sea-to-sea missiles,” Irani was quoted as saying by state TV, referring to an Iranian frigate sunk by the US on March 4.

On Wednesday, Tasnim quoted an unnamed military source as saying that Iran could open a new front at the mouth of the Red Sea if military action takes place on “Iranian islands or anywhere else in our lands”.

The source told Tasnim that Iran can pose a “credible threat” in the Bab al-Mandeb Strait, ⁠which lies between Yemen and Djibouti.

Tasnim later quoted an “informed source” claiming that Yemen’s Houthi rebels, backed by Iran, are prepared to play a role “if there is a need to control the Bab al-Mandeb Strait to further punish the enemy”.
