Feature: Yemeni students return to airstrike-hit school

Students leave school in Al-Radhmah district in Ibb province, Yemen, Dec. 23, 2019. The war in Yemen has forced more than two million children out of school and put 3.7 million others at high risk because of the non-payment of teachers' salaries, according to the United Nations Children's Fund (UNICEF). But for those who can return, they will risk everything in order to go back to the classrooms, even to sit on the rubble of airstrike-hit schools. (Photo by Mohammed Mohammed/Xinhua)
