Hong Kong tightened coronavirus restrictions on Sunday, with nonessential civil servants told to work from home from this week, as the global financial hub reported a record number of daily cases.

Earlier on Sunday, an event by pro-democracy politicians to mark the one-year anniversary of an attack in a train station by an armed mob was stopped by police in riot gear for breaking coronavirus measures already in place that restrict group gatherings to four people.

Hong Kong leader Carrie Lam told a news conference the city recorded more than 100 cases in the past 24 hours, the most since the pandemic took hold in late January, taking the tally close to 2,000 patients, 12 of whom have died.
