Spain's autonomous region of Catalonia has made face masks mandatory in public for all those aged over five after a surge in new cases of coronavirus.Anyone caught without a mask - even when social distancing can be observed - faces a €100 ($113; £90) fine.
It comes amid an outbreak of the virus in Segrià, an agricultural area.
Officials already imposed a lockdown on 210,000 residents on Saturday, banning anyone from entering or leaving except for work, BBC reported.
While the national situation is largely under control, Spain has been hit hard by the virus. As of Wednesday the health ministry said the country had recorded 252,513 cases and 28,396 deaths.
