Over a thousand Hong Kong school teachers braved thunderstorms on Saturday to start a weekend of anti-government demonstrations that some activists fear could see tougher police tactics on the city's streets. Following the escalation in violence during the past few days, the demonstrations this weekend will provide a litmus test as to whether the protest movement can retain the broad support that it has appeared to enjoy.
Demonstrators say they are fighting the erosion of the "one country, two systems" arrangement that enshrined some autonomy for Hong Kong since China took it back from Britain in 1997.
During the past week they have increasingly directed their frustrations toward police, who have responded with fiercer determination to clear them from the streets.
