Hong Kong leader says campus protesters must surrender

Hong Kong: Hong Kong's chief executive said Tuesday that protesters occupying a city centre university had to surrender if the three-day stand-off was to be resolved peacefully.

In her first public comments on the siege at Hong Kong Polytechnic University, Carrie Lam said she believed around 100 people remained at the campus, surrounded by police who were trying to quell the unrest.

"This objective could only be achieved with the full cooperation of the protesters, including of course the rioters that they have to stop violence, give up the weapons and come out peacefully and take the instructions from the police," she told a press conference.
