In western China, officials say they are fighting extremism by opening so-called "vocational training centres". But human rights groups argue these are actually mass detention camps, aimed at indoctrination and forcing people to renounce their faith. Up to one million people, mostly Uighurs, are thought to be held, but ethnic Kazakhs are also suffering from the consequences of the crackdown.
Meanwhile, a severe drought in western Afghanistan has displaced thousands of farmers. The weather is a devastating blow to livelihoods that were already threatened by decades of conflict.
And since August 2017, hundreds of thousands of Rohingya Muslims have fled a crackdown in Buddhist-majority Myanmar. The United Nations has described the violence as "ethnic cleansing" and "genocide". Many have sought refuge in the world's largest refugee camp in neighbouring Bangladesh, but even there, they continue to face danger.
