Protesters clash with police in China's Guangzhou

STORY: In one video obtained by Reuters, dozens of riot police in all-white pandemic gear, holding riot shields, were seen advancing in formation over what appeared to be torn down lockdown barriers as objects flew at them.

A separate video showed people throwing hard objects at riot police. Reuters was able to verify the location of the videos by matching the features of the buildings in the video with Street View on Baidu. However, Reuters could not determine the exact sequence of events and what sparked the clashes, as well as the date on which the videos were filmed.

The violent protests marked an escalation from demonstrations seen in Shanghai, Beijing, and other cities over the weekend in mainland China's biggest wave of civil disobedience since President Xi Jinping took power a decade ago.
