At least three attacks on commercial ships have been reported off the coast of Yemen and Oman since Wednesday. The attacks, carried out by the Yemen-based Houthis, have prompted US officials to call for a bolstered multinational naval force in the region. US Special Envoy for Yemen, Tim Lenderking, indicated that the Biden Administration was seeking the “broadest possible” coalition to protect ships traveling through the Gulf of Aden, Bab al-Mandab Strait, and the Red Sea. In response to the attacks, Iran, the primary backer of the Houthis, has warned that any US attempt to increase involvement in the region will not be tolerated. The attacks have raised concerns about the safety and security of commercial shipping in the region.
