A deepening sense of impasse gripped Hong Kong as pro-democracy protests entered their fourth week, with the government having limited options to end the crisis and demonstrators increasingly willing to confront police.
Dozens of people were reportedly injured in two nights of clashes that began late on Friday in the densely populated Mong Kok district of the Chinese-controlled city, including 22 police. Four people were arrested early on Sunday, police said.
The area was calm early on Monday, although scores of protesters remained on the streets.
