Unknown gunmen shot dead a security officer in Yemen's temporary capital, the southern port city of Aden which has been experiencing huge security challenges including since it was retaken from the Houthi militants last year.
A local news site quoted a provincial security source as saying on Sunday that the car of the emergency operations chief within the Aden Police Department came under a shower of bullets while the officer was driving in the Free Trade Zone.
"Colonel Taha Hussein and two guys who were with him including a woman died immediately and the perpetrators ran away before the authorities arrived at the scene," Al-Masdar quoted the source as elaborating.
The incident was the latest in a series of targeted killings since the government forces with support from the Saudi-led coalition liberated Aden from the Houthi militants in mid-2014.
It came a few days after the government and the coalition had revealed a plan to improve the security situation in Aden which has also been facing other security problems including presence of militant groups such as Al-Qaeda and ISIS.
ISIS claimed responsibility for deadly blasts including the one which killed the former Aden governor in early December.
The collation, which has been bombing Yemen since March, has deployed thousands of Arab troops and Yemeni troops trained in GCC states to secure Aden and help the government restore stability in the south.
