Hong Kong police and protesters faced off Monday as authorities began trying to clear the streets of a few hundred who remained near the city government headquarters after massive demonstrations that stretched deep into the night before.
The police asked for cooperation in clearing the road but said the protesters could stay on the sidewalks.
Protesters, many in masks and other gear to guard against possible use of tear gas, responded with chants, some kneeling in front of the officers.
The move came after activists rejected an apology from the city's top leader for her handling of legislation that has stoked fears of expanding control from Beijing in this former British colony.
Groups of police, most in normal uniforms not riot gear, sought to clear the roads of metal and plastic barricades to enable traffic to pass through. In some places, the protesters quickly moved to put them back to block traffic.
Hundreds of protesters were sitting or lying along a main road through downtown, but they were scattered over a relatively wide area.
Activists called on Hong Kong residents to boycott classes and work, though it was unclear how many might heed that call.
Nearly 2 million of the city's 7 million people turned out on Sunday, according to estimates by protest organizers.
Police said 338,000 were counted on the designated protest route in the "peak period" of the march.
