The UN Office for the Coordination of Humanitarian Affairs (OCHA) has appealed for 550 million U.S. dollars for Afghanistan to support the vulnerable people in the war-ravaged country in 2017. For Afghanistan's 30 million population, around 1.57 million people are reportedly food insecure, with 1 million children suffering from malnutrition. (Xinhua/Rahmine)
