A large group of protesters are holding an unlawful assembly in Tsim Sha Tsui, China's Hong Kong Special Administrative Region, police said in a statement, warning them to stop illegal activities immediately.

At around 3:00 p.m. local time on Sunday, rioters vandalized and hurled petrol bombs into Mongkok, Yau Ma Tei and Austin MTR Stations. Some even damaged the gate of a restaurant on Waterloo Road.

Some protesters set up barricades, blocking roads at Austin Road West and Jordan Road.

Police said they will conduct dispersal operations at the areas and warned the public to keep windows closed and stay indoors.
