Hijjah, 1431/Nov 26, 2010, SPA -- Seven people were injured after a suicide bomber struck a tribal convoy with a car bomb in north-western Yemen on Friday, tribal sources said. The sources told the German Press Agency dpa the attacker had rammed a car packed with explosives into the convoy in Sahar district of the north-western province of Saada early Friday. The convoy was carrying tribesmen to the funeral of Badruddin al-Houthi, the father of Abdul-Malik al-Houthi, the leader of a Shiite rebel group. Badruddin died on Thursday, they said. This is the second car bomb attack in the Shiite stronghold in northern Yemen this week. On Wednesday 15 people were killed in a similar attack.
