The Iranian military loaded naval mines onto vessels in the Persian Gulf last month, a move that intensified concerns in Washington that Tehran was gearing up to blockade the Strait of Hormuz following Israel’s strikes on sites across Iran, according to two US officials.
The previously unreported preparations, which were detected by US intelligence, occurred some time after Israel launched its initial missile attack against Iran on June 13, said the officials, who requested anonymity to discuss sensitive intelligence matters.
The loading of the mines – which have not been deployed in the strait – suggests that Tehran may have been serious about closing one of the world’s busiest shipping lanes, a move that would have escalated an already-spiralling conflict and severely hobbled global commerce.
About one-fifth of global oil and gas shipments pass through the Strait of Hormuz and a blockage would likely have spiked world energy prices.
Global benchmark oil prices have instead fallen more than 10 per cent since the US strikes on Iran’s nuclear facilities, driven in part by relief that the conflict did not trigger significant disruptions in the oil trade.
