In November, the Houthis in Yemen announced their intention to attack any ships associated with Israel, urging other countries to recall their crews from the vessels. The Houthis vowed to continue their attacks in the Red Sea until Israel ended its military actions in the Gaza Strip.
In December, US Secretary of Defense Lloyd Austin announced the establishment of a multinational operation to secure the Red Sea. The Houthis vowed to attack any ships that join the US-led maritime coalition.
