Unidentified gunmen have shot dead an officer in Yemen's southern port city of Aden in the latest attack targeting military personnel, a security official said on Friday.
Lieutenant Colonel Waleed al-Wahabi, a member of the special forces, came under fire late on Thursday in the Tawahi district, the official said.
Attacks targeting the security forces are on the increase in Yemen, but mainly take place in its lawless southern and eastern provinces, where jihadist groups are active.
Authorities have blamed Al-Qaeda in the Arabian Peninsula for a spate of drive-by shootings from motorbikes, but AQAP has never actually admitted carrying out such an attack.
On Wednesday, troops recaptured a military headquarters in the southern port city of Mukalla, after it was seized on Monday by Al-Qaeda-linked gunmen who also took hostages.
Twelve people, including five soldiers, were killed in the fight for the building.
