Barcelona and other cities in Spain's northeastern Catalonia region will impose a night-time curfew starting this weekend to fight a surge in virus cases after the measure won court approval on Friday.

Catalonia's top court gave the green light to restore a nightly curfew between 1:00 am and 6:00 am in areas where infection rates surpass 400 cases per 100,000 inhabitants over a 14-day period.
