Saudi soldiers stand at attention in front of tanks during a visit by Deputy Defence Minister Prince Khaled bin Sultan (unseen) at Al-Khoba in the southern Jizan province near the border with Yemen on January 27, 2010. Sultan said that Yemeni Shiite rebels were chased out of the kingdom and did not pull out on their accord as they claim. The leader of Shiite rebels, known also as Huthis, had announced on January 25 the voluntary withdrawal of his fighters from positions occupied within Saudi Arabia.
