Yemen: Suspected Houthi fighters attempt to seize sailboat near Hudaydah; STC and tribal forces refuse government military unit access to district in southern Yemen

Somalia: Gorgor secures villages in central Somalia; al Shabaab attempts to assassinate prominent Somali politician in Mogadishu; report reveals US-trained forces accidentally killed 22 civilians during infighting in northern Somalia in December 2021

Yemen Security Brief:

Suspected Houthi fighters may have attempted to seize a Hong Kong-flagged racing sailboat off the coast of Hudaydah, western Yemen, on May 19.[i] The fighters were likely not acting under orders from the Houthi movement. Key Houthi leader Muhammad Ali al Houthi denied responsibility for the attack on the sailboat.[ii]

Tribal forces and the Southern Transitional Council (STC)-aligned 111th Brigade refused to allow the Yemeni units under the Abyan Axis to enter Ahwar district, Abyan governorate, southern Yemen.[iii]

Somalia Security Brief:

Turkish-trained Gorgor special forces secured villages in Beledweyne district, Hiraan region, central Somalia, on May 19.[iv] Gorgor destroyed al Shabaab courts and bases in villages located between Beledweyne and Mataban. Al Shabaab left the villages before the security forces entered.

Al Shabaab detonated an improvised explosive device attempting to assassinate Somali politician Abdullahi Sheikh Hassan in Wadajir district, Mogadishu, on May 20.[v] Hassan survived the explosion and a local hospital is treating him.[vi] Al Shabaab militants targeted Hassan as he was leaving a mosque after Friday prayers.

Vice World News reported that the US-trained Puntland Security Forces (PSF) accidentally killed 22 civilians using US-supplied mortars during infighting in Bossaso, Bari region, northern Somalia, in December 2021.[vii] The Vice report said the mortars were for training, but that the PSF deployed them “wildly” and inaccurately. The Puntland president sparked the infighting when he attempted to dismiss the PSF commander and integrate the PSF as part of the regular state forces.[viii] Navy Seals mentor and train the US-created paramilitary force to target Islamic State and al Shabaab militants operating in the mountains of northern Somalia.

Yemen: Possible Houthi gunmen assassinate military officer in Ma’rib; Houthi militants attempt to assassinate military commander in Aden with VBIED; first flight departs Sana’a since 2016

Somalia: Biden authorizes the redeployment of SOF to Somalia and Pentagon targeting of al Shabaab leaders; Burundian ATMIS forces abandon base in southern Somalia to consolidate forces in response to al Shabaab’s May 3 raid

Yemen Security Brief:

Possible Houthi gunmen assassinated a 159th Infantry Brigade staff officer in Ma’rib City, central Yemen, on May 14.[i]

Likely Houthi militants detonated a vehicle borne improvised explosive device (VBIED) targeting the head of Joint Operations in the 4th Military Region in Mualla district, Aden city, southern Yemen on May 15.[ii] The VBIED did not kill the officer, who was riding in an armored car.[iii] Local officials in Aden said the explosives used in the attack were less powerful than the explosives in previous attacks targeting military officers. The Yemeni government accused the Houthis of working with al Qaeda in the Arabian Peninsula for the attack.[iv]

A Yemenia Airways flight to Amman, Jordan, on May 16 was the first flight from Sana’a International Airport since 2016.[v] Reopening Sana’a International Airport was one of the stipulations under the UN-brokered truce that began in early April.

Somalia Security Brief:

US President Joe Biden authorized the redeployment of special operations forces to Somalia in early May and granted the Pentagon standing authority to target nearly a dozen al Shabaab leaders.[vi] The order allows for the redeployment of “hundreds” of special force personnel according to anonymous US officials. Former President Donald Trump withdrew US forces from Somalia in January 2021 and adopted an over-the-horizon posture, operating from Kenya and Djibouti. US forces historically gave training, advisory, and logistical support to the Somali National Army Danab special forces. The leak comes less than 24 hours after Somalia elected a new president more than one year after the original election date.[vii]

Burundian ATMIS forces abandoned a forward operating base near Gululei, Balad district, Middle Shabelle, southern Somalia, on May 14.[viii] Al Shabaab immediately took over and looted the base. The troops redeployed to reinforce bases near Bal’ad, Jowhar, and two other towns in Middle Shabelle.[ix] The move is reportedly to prevent al Shabaab from overrunning another base in Middle Shabelle. Al Shabaab overran El Baraf base, Middle Shabelle, on May 3.[x]
