Yemen’s Houthi rebels today launched a missile attack on a Greek-owned cargo ship sailing off the port of Hodeidah, without causing casualties or damage, according to Agence France-Presse (AFP) citing maritime security companies.

According to the information center of the multinational naval force deployed in the area, the attack was launched against the Maltese-flagged bulk cargo ship YANNIS. It is owned by the Greek shipping company Eastern Mediterranean Maritime Limited, the website Marine Traffic reports. The ship had departed from Russia bound for Kenya.

Since last November, Iran-aligned Yemeni rebels have frequently launched missile and drone attacks against merchant ships in the Red Sea and Gulf of Aden. They initially said they were targeting ships linked to Israel, but later expanded their targets to include ships linked to the US and Britain in retaliation for strikes against their positions in Yemen by forces from those countries.

Houthi attacks in the Red Sea region have caused problems for global shipping, forcing companies to send their ships on time-consuming and more expensive voyages around southern Africa.
