SANAA (Reuters) - At least eight people were killed north of the Yemeni capital Sanaa on Tuesday in fighting between Shi'ite Muslim tribesmen and Sunni Muslim rivals and the army, local government sources said.
Bouts of intense sectarian conflict since last year have undermined attempts at national reconciliation in Yemen, a neighbour of major oil exporter Saudi Arabia and home to one of al Qaeda's most active wings.
