British authorities and naval intelligence sources have reported two incidents that are likely to be the first attacks by the Houthis against merchant ships in the Red Sea in a month. A separate attack on another ship was reported at 04:15 (local time), 97 miles northwest of Hodeidah.

A drone boat loaded with explosives crashed into a ship Tuesday in the Red Sea, the British military and private security officials said, the latest suspected attack by Yemen’s Houthi rebels. The drone attack and an earlier attempted attack Tuesday likely are the rebels’ first assaults on commercial shipping in weeks as the Israel-Hamas war threatens to become a regional conflict.
