The war, waged by a Saudi-led coalition in 2015, and the ongoing Saudi blockade of Yemeni ports have brought hunger and disease to the civilians there. Relief group Save the Children estimated that an average of 130 children under the age of 5 are dying each day, one every 10 minutes. /Chinanews Photo

World Children's Day was established in 1954 and is celebrated to raise awareness of and improve children's welfare. /Chinanews Photo
