At least 5 people were killed and injured after a car bomb was exploded at the residence of the security director of Yemen's temporary capital Aden on Sunday, local officials told the Yemen Post.
Two guards of the residence located in the district of Al-Tawahi and the driver of the car bomb were killed and two other guards were injured, they said.
The attack was the latest in a series of targeted killings and blasts in Aden since it was retaken from the Houthi militants in mid-2014.
The southern port city has been experiencing huge security challenges including a rise in targeted killings and presence of militant groups such as Al-Qaeda and ISIS.
The two militant groups claimed responsibility for some attacks including the car bomb killing former Aden governor in early December.
Other attacks were carried out by unidentified gunmen.
Today, news reports said the police director of the province of Baidha was killed in a bomb that had been placed in his car.
In recent weeks, targeted killings were reported in the capital Sanaa and other cities.
In the capital, three Houthi loyalists were shot dead by gunmen on motorbike. More Houthi fans were killed in Hodeida and Marib.
The killings came amid deepening security vacuum due to the ongoing conflict between the government fighters and the Houthi militants.
