Photo taken on Feb. 23, 2017 shows one of the families living in mud buildings, in the northern urban district of Kabul, Afghanistan. Winter has almost blanketed Afghanistan, affecting the lives of poor families, particularly those who have no warming equipment, clean water or enough food to cope with the cold weather. In the northern urban district of Kabul, many are still living in mud buildings, and have no money to purchase any wood to fire. (Xinhua/Dai He)
