HONG KONG (AP) — A pro-democracy protest that has blocked main roads in Hong Kong for almost two weeks could drag on for days yet, after talks aimed at resolving a bitter standoff between the city’s government and student demonstrators collapsed Thursday.

The government called off the talks hours ahead of the scheduled time Friday, saying the dialogue had been “seriously undermined” by student leaders’ call earlier in the day for supporters to turn out in force to occupy the main protest zone.
