HONG KONG - Hong Kong’s rail operator partially reopened the city’s metro system Sunday after an unprecedented shutdown but kept many typically busy stations closed as the Chinese territory braced for large demonstrations later in the day.

Violent protests erupted across the Asian financial center Friday hours after its leader Carrie Lam invoked colonial-era emergency powers, last used more than 50 years ago, to curb months of unrest.

The night’s “extreme violence” justified the use of the emergency law, Beijing-backed Lam said in a television address Saturday.

The city felt eerily quiet Saturday with the subway and most shopping malls closed and many roads deserted. Hundreds of anti-government protesters defied a ban on face masks and took to the streets across the city earlier in the day, but by evening they had largely dispersed.

The former British colony has been roiled by increasingly violent protests for four months, which began in opposition to a bill that would have allowed extradition to mainland China but have spiraled into a broader pro-democracy movement.

Hong Kong’s rail operator MTR Corp said that because of serious vandalism some stations will not be opened for service Sunday, as damaged facilities needed time for repair. Train service would also be shortened to end at 9 p.m., more than three hours earlier than normal.

The operator’s closure Saturday had largely paralyzed most of the city with its network typically carrying about 5 million passengers a day.

Supermarkets and commercial stores that shuttered Saturday had mostly reopened by Sunday morning.

Many restaurants and small businesses have had to repeatedly shut with the protests taking a growing toll on Hong Kong’s economy as it faces its first recession in a decade.

Two major protests are planned for Sunday afternoon, one on the island and another on the Kowloon Peninsula with many demonstrators expected to defy a ban on face masks.

Beijing-backed Lam said a ban on face masks that took effect Saturday was ordered under the emergency laws allowing authorities to “make any regulations whatsoever” in whatever they deem to be in the public interest.

The move enraged protesters, who took to the streets Friday night to vent their anger, many wearing masks in open defiance.

Some set fires, hurled petrol bombs at police and burned the Chinese national flag, in a direct challenge to authorities in Beijing.
