Protests in China against government's strict Covid measures have intensified, with some people publicly venting their anger at the Communist Party leaders, BBC reported.

Thousands of protesters have turned out in Shanghai, where the BBC has seen people bundled into police cars.

People gathered again Sunday, laying flowers for the Urumqi fire victims in the area of Shanghai's Urumqi Road.

Students have also demonstrated at universities in Beijing and Nanjing.

The latest unrest follows a protest in the remote northwest city of Urumqi, where lockdown rules were blamed after 10 people died in a tower block fire.

While Chinese authorities deny that Covid restrictions caused the deaths, officials in Urumqi did issue an unusual apology late on Friday, and pledged to "restore order" by phasing out restrictions.
