The attacks on Saudi energy facilities by the Iranian-backed Houthisthreaten oil shipments on the Red Sea. This has been a key alternative route to the Strait of Hormuz path.

Meanwhile, the US attacked Iranian oil tankers in the Gulf of Oman and in the Strait of Hormuz. "Iran has used the tankers as part of a multibillion-dollar shadow network that funds the IRGC and its regional proxies," CENTCOM said in a statement.
