US forces on Tuesday carried out fresh strikes on targets linked with Houthi militants in Yemen, amid disruption to global trade caused by cargo ships diverting to avoid the Iran-backed group’s attacks in the Red Sea.

The US military’s Central Command said its forces struck and destroyed four anti-ship ballistic missiles that the Houthis had prepared to launch from Yemen in the early hours of Tuesday. It was the third round of strikes by American forces on Houthi targets in Yemen in less than a week as the US seeks to deter the rebel’s attacks on shipping in the key waterway.

However, the Houthis still succeeded hours later in launching a missile that struck the Zografia, a Greek-owned Maltese-flag ship for carrying dry bulk commodities, which was sailing towards the Suez Canal. That followed Monday’s missile strike on another bulk carrier in the Gulf of Aden.
