The dawn strike targeted their car as it left the base of the 27th Mechanised Brigade in the Hadramawt provincial capital Mukalla, the official told AFP.
Fighters from the extremist group had seized the camp from forces loyal to President Abedrabbo Mansour Hadi in April, consolidating their grip on Mukalla.
