Four civilians and two soldiers were shot dead and 10 others wounded by security forces in the southern Yemeni port city of Aden on Friday, southern separatists and an official said, as crowds gathered calling for the separation of the south.
A local security official said three soldiers including a lieutenant were among those hurt at a festival to mark the anniversary of a violent struggle for an independent south which led to civil war and began in Aden on January 13, 1986.
The crowd at the festival was shouting "Revolution! Revolution! Oh South!", witnesses said.
