PV International Desk : Two people were in critical condition in Hong Kong, police said on Monday, after a weekend of chaotic clashes with anti-government protesters, as China called for a “tougher” stance to end months of unrest that have roiled the Asian financial hub.

Riot police stormed several shopping malls on Sunday, including Cityplaza, packed with families and children in the eastern suburb of Taikoo Shing.

Protesters there had initially formed a peaceful human chain before facing off with police in skirmishes up and down escalators and spraying graffiti on a restaurant.

A man with a knife slashed several people and apparently bit off part of the ear of a politician. The wounded included a man believed to be the knife-wielder, whom protesters had beaten with sticks.
