Hanoi entered a 15-day lockdown on Saturday to combat a new Covid-19 wave linked to the highly contagious Delta variant, the worst the country has faced since the start of the pandemic.

The lockdown of the Vietnamese capital, which has more than 4.6 million inhabitants, was announced unexpectedly on Friday night amid a sudden spike in infections in the last 48 hours.

Residents have been ordered to stay home and only step out under few exceptions, such as to buy food or to go to the hospital.
