Iranian state media reported explosions on Saturday evening on Qeshm Island and in Jask, Bandar Abbas and Sirik, in or near Hormozgan province and the Strait of Hormuz.

The reported sites are near a major global oil-shipping chokepoint; Bandar Abbas is a principal southern port, while Qeshm, Jask and Sirik sit along the strait and the Gulf of Oman coast.

Earlier on Saturday, Donald Trump confirmed a U.S. “minor strike” on Qeshm Island, while Tasnim reported that two missiles had hit the island overnight.

A U.S. official said a limited strike on Qeshm Island on Monday had been ordered after Iran’s Islamic Revolutionary Guard Corps tried to target an American aircraft with a missile launched from the island.

The cause and nature of the newly reported explosions remained unconfirmed; ISNA said they could be linked to Iranian military actions in the Strait of Hormuz.

Initial reports provided no further details about casualties or damage, and did not identify responsibility for the explosions.

Separately, U.S. Central Command said a precision munition struck and disabled the M/V Huda after it tried to evade a naval blockade, while Iranian state television reported that two oil tankers had hit mines near the Strait of Hormuz.

Al Jazeera’s live coverage also reported that the United States was moving to block land supply routes into Iran, without specifying the routes or neighboring countries involved.

The BBC reported that the United States had offered up to $20 million for information about Iran’s nuclear program.

The BBC also reported that Donald Trump had repeatedly raised the prospect of renewed U.S. strikes on Iran’s nuclear facilities, which the United States had attacked earlier in the conflict.

The report described expectations that U.S. attacks on Iran could resume after Tuesday’s midterm elections, while Iran had threatened retaliation against U.S. and Israeli targets in neighboring countries.
