"A suicide bomber in a car detonated as the convoy of the governors of Aden and Lahj provinces along with the Aden security director passed through the area of Inma," Nizar Anwar, a government spokesman said.
Three soldiers were killed in the exchange of fire which followed the attack, security sources said, before the assailants retreated into the surrounding desert.
