Unprecedented protests against Covid restrictions broke out in China overnight on Friday, with hundreds taking to the streets in Xinjiang's capital amid anger over a deadly fire.Videos showed people in a plaza singing China’s national anthem, likely as a form of protection against being accused of being against the government.Xinjiang has been the site of one of China’s toughest and longest Covid lockdowns, with many of Urumqi's 4 million residents having been prevented from leaving their homes for as long as 100 days.The unrest in Xinjiang will be of particular concern to Beijing as it is the site of a years-long repression campaign against ethnic minorities that the UN has said may have amounted to "crimes against humanity".The protests are just the latest example of Chinese communities' anger and fatigue with seemingly never-ending Covid restrictions boiling over."
