Feature: Yemeni pupils take classes outside crumbling school building amid bitter winter

Students take class at the Yahya Mathkour School in Al-Rahabah area on the northern outskirts of Sanaa, Yemen, on Dec. 3, 2019. During the nearly five years of civil war which has destroyed Yemen's education system, 2 million school-aged children in the country were forced out of school, while 3.7 million others are facing this risk because of the non-payment of teachers' salaries, according to the UNICEF.
