Mohammed bin Salman (R) has asked Donald Trump (L) for more military support to counter the Houthis. The U.S.-Iran war has reached crisis point for Saudi Arabia and its de facto leader, Crown Prince Mohammed bin Salman. The kingdom was spared the worst of the Islamic Republic's counterstrikes against the U.S. and Israel early in the conflict, and was even benefiting from higher crude prices as it used a land pipeline to bypass the Strait of Hormuz. That all changed when the Houthis started firing at Saudi Arabia on a near-daily basis this month. The Iran-backed militants have also captured more territory in Yemen, where they are based, tightening their control over Bab el-Mandeb, another vital strait for shipping and energy markets.

Did Iran capture a US submarine? Saudi Arabia has temporarily closed its critical East-West oil pipeline, a 1,200km (746-mile) conduit stretching across the Arabian Peninsula, after it was attacked by drones on Friday. The drones were reported to have been launched from Iraq, where an investigation is under way. No group has claimed responsibility for the strikes so far. It is understood that equipment used to operate the pipeline was also hit.

Saudi Arabia has closed a critical oil pipeline after it was attacked by drones launched from Iraq, as conflict in the Middle East widens. Iraq said it had fired a military commander and launched an investigation after admitting the drone attack on its neighbour's East-West pipeline had originated in one of its provinces bordering Iran. The 1,200km (745 mile) pipeline has helped Saudi Arabia - the world's largest crude oil exporter - bypass the Strait of Hormuz. The incident comes amid a major advance by the Iranian-backed Houthi rebels in Yemen, putting more pressure on global oil shipping routes as the US-Iran war stretches into its seventh month. Riyadh on Friday said it had shut the pipeline as a precaution, as satellite images of scorched ground and smoke near the site emerged.

Chevron and Williams are big winners in the race to power artificial intelligence as they build out gas-fired power plants and pipelines. It's been a banner year for oil and gas companies. Some of the world's biggest oil giants have announced billions of dollars in quarterly profits over the past two weeks, boosted largely by the soaring price of oil thanks to the conflict in the Middle East. But the artificial intelligence boom is also giving fossil fuel companies a new industry to sell their gas, pipelines, and power plants to: data centers . Two American oil and gas companies, Williams and Chevron, are presenting that demand to investors as a huge win.
