Chinese authorities are tightening security in the western region of Xinjiang just days ahead of the one-year anniversary of the country’s worst ethnic violence in decades.
Officials in the city where nearly 200 people were left dead last year said they installed about 40,000 high-definition surveillance cameras with “riot-proof” shells in public spaces.
Tensions between Xinjiang’s minority Uighurs and majority Han Chinese turned deadly in the city of Urumqi last July 5.
The government said 197 people were killed. Beijing blamed overseas Uighur groups of plotting the violence, but exile groups denied it.
The surveillance cameras follow a “strike hard” crackdown on violent crime launched last month, and hiring of about 5,000 new police officers in Xinjiang.
