Saudi Arabia and the United Arab Emirates reported coming under fresh attacks on Monday morning, with explosions and sirens sounding over the oil-rich Gulf.

The Saudi Ministry of Defence said it had detected two incoming ballistic missiles targeting the capital on Monday, “one of which was intercepted and the other fell in an uninhabited area”.

The UAE defence ministry said it was “currently responding to incoming missile and drone threats from Iran”, explaining “the sounds heard are the result of the Air Defence Systems intercepting missiles and drones”.

Hours earlier, Abu Dhabi authorities reported an Indian national had been wounded by falling debris from an intercepted ballistic missile.

And sirens were sounding in Bahrain, with residents instructed to seek shelter.

“Citizens and residents are urged to remain calm and head to the nearest safe place,” the interior ministry posted on social media.

In Iran, a strike on a broadcast station in southern Iran killed at least one person, state television reported on Monday.

“The 100-kilowatt AM transmitter of the Persian Gulf Radio and Television Centre was attacked by the American-Zionist terrorist army,” the state-run Islamic Republic of Iran Broadcasting reported.

“In this attack, which was against international laws, one of the centre’s security colleagues was martyred and another person was injured.”

In a post on Telegram, Israel’s military said it had “begun a wide-scale wave of strikes targeting Iranian terror regime infrastructure in Tehran”.

A thick plume of black smoke could still be seen billowing from one point in eastern Tehran, an AFP journalist reported.

Gulf nations that have long billed themselves as oases of safety and stability in the region have been drawn into the Middle East war as Iran retaliates against US-Israeli strikes.

The Islamic Republic has taken aim at US assets as well as civilian infrastructure, including landmarks, airports, ports and oil facilities around the Gulf.

The benchmark US oil contract WTI was up on Monday after US President Donald Trump gave Iran a 48-hour ultimatum to open the Strait of Hormuz or face decimation of its energy infrastructure and Israel warned the war would continue for several more weeks.

At 00:15 GMT, the price of West Texas Intermediate (WTI) was up 0.44% to $98.66 per barrel.

It had climbed to just over $100 a barrel earlier on Monday.
