Students of Grade 6 attend class at Olomayiana West Primary School in Kajiado County, Kenya, Feb. 15, 2017. Ten of their classmates were gone because they needed to migrate with their parents to find better grassland to feed the cattle in the lasting drought. The Kenyan government last Friday declared the current drought affecting 23 arid and semi-arid counties and pockets of other areas a national disaster. The UN Food and Agriculture Organization (FAO) have warned that Kenya is facing a severe drought and with it a rise in food insecurity. (Xinhua/Sun Ruibo)
