Saudi airstrikes killed three people, including two children, and wounded two others in Yemen’s Taiz province, a Houthi health ministry spokesperson said Tuesday.

Anees al Asbahi said in a post on X that the strikes were carried out by Saudi warplanes. The claim could not be independently verified, and the Houthis did not say what was targeted.

The reported strikes came as Houthi forces expanded their control over strategic areas in the Red Sea, including the Greater and Lesser Hanish islands, after capturing the port of Mokha and another strategic island last week.

The developments are raising concerns over shipping through the Red Sea and could put further pressure on global oil supplies as disruptions continue in the Strait of Hormuz.

Meanwhile, Human Rights Watch said at least three Houthi attacks on commercial vessels between July 20 and Aug. 24 could amount to war crimes. The rights group urged the Houthis to immediately halt unlawful attacks on civilian ships.

Oman’s Maritime Security Center said a Panama-flagged oil tanker, the El Gaia, was towed to port after being targeted. A fire broke out in its engine room, 23 crew members were evacuated and two remained missing.

Separately, Saudi Crown Prince Mohammed bin Salman visited Cairo for talks with Egyptian President Abdel-Fattah el-Sissi, while Turkish Foreign Minister Hakan Fidan called for renewed diplomacy and the restoration of safe and uninterrupted passage through the Strait of Hormuz.

China also said Iranian Foreign Minister Abbas Araghchi would visit Beijing on Wednesday for talks with Chinese Foreign Minister Wang Yi.
