SANAA, Yemen -- A Yemeni security official says soldiers have killed six Al Qaeda-linked fighters in a southern city.

Months of battles have failed to fully restore the government's control over the city of Zinjibar.
It is one of several places in the south seized by Islamic militants during the spiraling unrest triggered by the uprising against President Ali Abdullah Saleh.

The security official says six soldiers were wounded in Saturday's fighting.

The official was speaking on condition of anonymity because he was not authorized to brief reporters.

Anti-government protests continued Saturday.
