Tens were arrested on Saturday in Yemen's business capital of Aden as people poured onto streets to protest against routine blackouts.

Eyewitnesses told the News Yemen that hundreds of people gathered from various areas in the port city burning tires and demanding to return electrical power to their homes and shops.

Anti-riot police fired bullets in the air and used water hoses to break up the protest that came amid heatwave hitting Aden.

The protestors complained that blackouts take place many times a day; in some cases outages last for more two hours.

Separately, fierce clashes broke out today between armed separatists and security forces in the district of Malah, Lahj, in which two people were run over and died and three others were injured including a child.

A shop was also burned and other damages were reported in the confrontations as well.

On the other hand, the local council in the district of Radfan reopened on Sunday Dhale-Radfan road that has been closed by separatists for 14 days.

Life returned normal in the area, with supplies allowed in for the people.

In recent weeks, separatists set up checkpoints in many areas in the province using them to attack police and commit vandalism.
