From Syria to Yemen and Iraq, from South Sudan to Nigeria, children are affected by relentless conflicts and displacement crises, as well as devastation wrought by natural disasters. To reach those in greatest need, US$3.3 billion is needed by UNICEF to assist 81 million people in 2017, including 48 million children in 48 countries across the globe.
Here are some of these children:

After 20 days of therapeutic feeding to treat severe acute malnutrition at a UNICEF-supported clinic, Umara increased his weight from just 4.2kg to 5.1kg. Umara is assessed for malnutrition at Muna Garage camp for internally displaced persons in north-east Nigeria.
Lying on a bed in the Abs hospital in Yemen's Hajjah governorate, five-year-old Mohanned is suffering from severe acute malnutrition. Although Mohanned's health has been deteriorating for the past two years, his family were unable to afford the cost of bringing him for treatment.
Despite setbacks, more than 300,000 children in South Sudan were provided with access to education in 2016. In the Protection of Civilians site in Malakal, twelve-year-old Chubat (right) sits with her friend in the burnt-out ruins of a UNICEF-supported primary school she attended.
"I thought I was going to die. I thought my family would all die" said Mylove Théogène (right), 8, after hurricane Matthew destroyed her home in Jérémie, Haiti. More than 175,000 people were displaced by the tropical storm and more than 800,000 require life-saving assistance.
