In northern Yemen, Shia Houthi fighters have overrun the strongholds of pro-Salafi tribal militants. Local sources say Houthis have taken control of the town of Houth as well as Khamri village from tribal gunmen in the north. The move is considered a major advance for the Shia fighters following weeks of battles with pro-Salafi militants. Houthi fighters and gunmen from the Hashid tribe have been engaged in heavy fighting since early January. Hundreds of people have lost their lives in the clashes since last October. Show Less >>
