HONG KONG (AP) — Calm appeared to have returned to Hong Kong after days of protests by students and human rights activists opposed to a bill that would allow suspects to be tried in mainland Chinese courts.

The prospect of further protests over the weekend loomed large, however, with demonstrators saying they were determined to prevent the administration of Beijing-appointed Chief Executive Carrie Lam from pushing through the legal amendments they see as eroding Hong Kong's cherished legal autonomy.

Traffic flowed on major thoroughfares that had been closed after a protest by hundreds of thousands of people on Sunday, posing the biggest political challenge yet to Lam's two-year-old government. Protesters had kept up a presence through Thursday night, singing hymns and holding up signs criticizing the police for their handling of the protests.
