A number of Spanish regions are reintroducing curfews and also tightening restrictions on social gatherings. This is happening since bars and restaurants have reopened in the evenings, which has resulted in an increased number of infections of the delta variant.

According to Reuters Are primarily unvaccinated young people being infected?.

Catalonia and Valencia have now lowered the ceiling for how many people can meet. The maximum limit is now ten people. 

In the northern region of Asturias, indoor bars and restaurants are no longer permitted.
