Hong Kong: More than 1000 people, mostly students dressed in black, rallied outside government offices in Hong Kong on Friday as protests over a controversial extradition bill that has plunged the Chinese-ruled city into turmoil showed no signs of let-up.

Embattled Hong Kong leader Carrie Lam suspended the bill, that would allow people to be sent to mainland China for trial, after some of the largest and most violent protests in decades, but she has stopped short of protesters' demands to scrap it.

The activists have seized on the G20 summit of world leaders in Japan this week to appeal for the former British colony's plight to be put on the agenda, a move certain to rile Beijing, which has vowed not to tolerate such discussion.

"The government hasn't given a proper response to the public. It's the government who forces us to come out," said Paul Chan, 27.
