IRAN’S paramilitary Revolutionary Guard threatened today to halt all energy exports from the Middle East after the United States reimposed a naval blockade on the country and intensified its campaign of air strikes.

“The export of oil and gas from the region will be either for everyone or for no-one,” it said.

Following Iranian attacks on ships trying to pass through the Strait of Hormuz, the United States carried out a wave of strikes, hitting dozens of targets overnight, the military’s Central Command said today, before resuming action against Iran during daylight.

An Iranian army barracks was hit, killing at least seven soldiers, while more than 260 people were wounded in other attacks, Iranian officials said.

Days of strikes by the US and Iran and renewed threats to the strait — through which a fifth of the world’s oil and natural gas moves during peacetime — have shredded an interim peace deal and left the region on the brink of a return to all-out war.

Within 17 hours of reimposing the blockade on Iranian ports, US Central Command said its forces had “redirected” two commercial vessels attempting to run the blockade.

Among the US targets was Greater Tunb Island, viewed as a strategic point in the Strait of Hormuz.

Another strike targeted a barracks of Iran’s 388th Mechanised Infantry Brigade in Sistan and Baluchestan province.

Iranian state television reported that US forces had fired at least 13 missiles in the attack and that the seven dead included conscripts and career soldiers. A number of troops were wounded.

Including those at the barracks, more than 30 people have been killed in recent days, Iranian government spokesman Fatemeh Mohajerani said.

Health Ministry spokesman Hossein Kermanpour said that more than 260 people had been wounded in overnight strikes alone.

Missile alert warnings sounded in Bahrain and Kuwait early today as they faced incoming Iranian fire. Jordan reported shooting down three Iranian missiles. All those countries host US forces.

US President Donald Trump told the Fox News Channel on Tuesday night that more US strikes would come over the next two days and that bridges and power stations could be targeted by next week unless negotiations resume. At least one bridge has already been hit.

“You better make a deal, or you’re not going to have anything left,” he threatened.

However, Mr Trump dropped his warning that the US could charge ships using the strait a 20 per cent toll, saying instead that he would strike “trade and investment deals” with US Gulf allies.
