President Joe Biden joins a solemn military ritual at a Delaware air base for the return of three US soldiers killed in Jordan by a drone attack blamed on an Iran-backed militia. Six servicemen wearing camouflage, dark berets and white gloves march slowly three times on and off the ramp of a huge C-5 transport plane to carry the remains in flag-draped transfer cases -- as the military calls caskets used in transportation -- to a waiting van. Biden, accompanied by First Lady Jill Biden, watches with his hand over his heart and a grim expression. Family members watched from their own area, screened off from the press. IMAGES
