Yemeni protesters rally in front of the house of the Yemeni president during a demonstration in Sanaa against conflicts between Shiite Houthi rebels and Salafi militants in northern Yemen, on Nov. 2, 2013. At least nine Sunni Salafists were killed and five others injured on Thursday in an armed attack by Shiite Houthi rebels in Yemen's northern province of Saada, a tribal chief told Xinhua. The Shiite Houthi rebels have been involved in sectarian clashes with armed Sunni tribesmen for years, forcing thousands of Sunni residents to flee the area. (Xinhua/Mohammed Mohammed)
