UNITED NEWS INTERNATIONAL (UNI) — One U.S. Army soldier was killed and four other were wounded in a firefight with al-Shabab militants in Somalia.

Twenty-six-year-old Staff Sgt. Alexander Conrad died on June 8 of injuries from “enemy indirect fire.”

According to the Pentagon, Conrad and other U.S. troops were operating alongside Somali National Security Forces and Kenyan Defense Forces in southern Somalia when they came under mortar and small-arms fire.

U.S. President Donald Trump took to Twitter on Friday to express his condolences, calling Conrad and other wounded soldiers “HEROES.”

Conrad was posthumously awarded a Purple Heart and Meritorious Service Medal.

The incident marked the first reported U.S. military combat death in Africa since four U.S. service members were killed in October in an ambush in Niger.
