Following the Houthis group’s attack on international ships in the Red Sea, the United States and the United Kingdom launched a joint strike in Yemen. In April 2024, Iran was said to have launched a drone attack on Israel after the latter attacked Iran’s foreign consulate in Syria. While the conflict was contained at initial stages, a risk of further escalation still looms. The Bank seeks to manage the associated impacts on its customers and business. </div></div></div>
