Hong Kong: Hong Kong's embattled leader Carrie Lam condemned the takeover of the city's legislature by protesters as an "extreme use of violence" and vowed to go after those who trashed the building and fled before the riot police moved in.

Chief Executive Carrie Lam said she was "angry" and "saddened" by Monday's violence during which protesters rammed the glass facade of the Legislative Council building before storming into the main parliamentary chamber and vandalising property. Hundreds of policemen had to use tear gas to clear the building.
