In October 2023, the Yemen-based and Iran-backed Houthi movement started a series of attacks (continuing well into 2024) against several vessels navigating the Red Sea, with the declared intention to support the population of Gaza in the rekindled Israeli-Palestinian conflict. On 10 January 2024, the United Nations Security Council adopted Resolution 2722, taking note of “the right of Member States, in accordance with international law, to defend their vessels from attacks, including those that undermine navigational rights and freedoms”. This ambiguously-worded text does not provide for an autonomous legal basis for reaction and leaves open the question of the legality of the forcible measures subsequently taken by (mostly Western) States.
