At least four pro-government fighters were killed in a suspected IS suicide bomber attack in Yemen's southern port city of Aden on Monday afternoon, an official told Xinhua.
The bomber blew himself up at a checkpoint manned by the Popular Resistance, an anti-Houthi militia, in Aden's neighbourhood of Mansoura, the local official said on condition of anonymity.
Initial reports indicate that four fighters were killed while two were critically injured at the scene, the source said.
Aden's newly appointed governor on Friday banned the carrying of weapons in the city. Hundreds of Sudanese soldiers from the Saudi-led Arab coalition were deployed near government facilities and set up military checkpoints in neighbourhoods in order to confiscate weapons.
So far no group has claimed responsibility for the suicide attack that targeted the Popular Resistance for the first time, but local security sources blamed the IS terrorist group.
