- Pro-Islamic State in Iraq and al Sham (ISIS) militants belonging to ISIS Wilayat Sana’a detonated an improvised explosive device (IED) attack targeting al Houthis at a Zaydi mosque in the capital, Sana’a, on May 22. The attack reportedly wounded 13 people. The same day, suspected pro-ISIS militants detonated a suicide vest (SVEST) targeting a Shi’ite mosque in al Qatif, Saudi Arabia, killing an estimated 20 people and wounding 50 others. It remains unclear if the attacks were coordinated. ISIS militants previously detonated four SVESTS in Yemen at mosques on March 20, killing upwards of 130.

Al Houthi militants also fired rockets at al Dharan, Saudi Arabia, on May 21 killing two Saudi citizens and wounding two others.
- Unidentified militants attempted to assassinate the governor of al Hudaydah in al Hudaydah city on May 22. The attackers reportedly killed one person, and injured two of the governor’s bodyguards, though he himself was unharmed. No group has claimed credit for the attack.
