A boy, displaced by the ongoing fighting in northwestern Yemen, carries his sister outside their family's tent in al-Mazraq refugee camp near the Saada province October 4, 2009. Around 6,000 people live in the camp after they were forced to leave their villages by the new wave of fighting in the intermittent five-year-old conflict between rebel Shi'ite Muslims and the government forces that has added another 50,000 people to 100,000 or so left homeless earlier by fighting in the poorest Arab nation, mostly women and children, according to estimates by U.N. agencies.(Xinhua/Reuters Photo)
