Strait of Hormuz and Red Sea risks intensify
The U.S. military said it carried out a 12th consecutive night of attacks on Iran hours after U.S. President Donald Trump's vowed to destroy an Iranian bridge or power plant every time Iran shoots at a ship in the Strait of Hormuz, raising the stakes in the war with Iran.
Iran's Revolutionary Guards said that an oil tanker had caught fire after an explosion while attempting to pass through what they described as a mined route south of the Strait of Hormuz, and that the two other tankers had turned back.
The Guards said the strait was under their control and "completely closed" while U.S. actions continued in the region, warning that no tanker would be allowed to enter or leave without coordination with Iran.
As well as the renewed conflict over control of that key waterway, the Iran-aligned Houthis have opened a new front in the war by threatening to target vessels carrying Saudi oil in the Bab el-Mandeb Strait and announced a naval blockade of Saudi Arabia.
The Houthis said they had carried out a military operation targeting two Saudi oil tankers, and maritime security reports said one of the vessels named by the group, the Saudi-flagged tanker Encelia, had been hit in the Red Sea.
The Houthis said they had forced around 10 ships to retreat and return after warning vessels against sailing to Saudi ports. Reuters could not immediately verify this account.
The Houthis' naval blockade on Saudi Arabia in the Red Sea threatens to disrupt global energy supplies beyond the Gulf, while Iran's Revolutionary Guards' spokesperson also warned shipping companies that the Strait of Hormuz southern route is mined in a post on X.
