The island of Taiwan, which has had enviable success in containing Covid-19, imposed new restrictions in its capital city on Saturday as it battled its worst outbreak since the pandemic began.

Authorities raised the alert level for Taipei, the capital, and the surrounding area of New Taipei city. The level 3 alert, which remains in effect for two weeks, requires people to wear a mask outdoors and limits indoor gatherings to five people and outdoor gatherings to 10 people.
