As of today, Friday 21 August, everyone over the age of 11 in Gibraltar must wear a mask inside shops and stores unless they have a medical condition or disability which exempts them from doing so.
Masks are recommended for children under 11 as well, but in their case they are not compulsory.
Shop staff already have to wear masks, but until now customers have not had to do so.
Another new measure is that bars have been told they must close by 1am in future, with last orders at 12.30am
The move to tighten restrictions comes as the number of Covid-19 cases in Gibraltar continues to rise. The authorities say many recent cases have been among young people who have been socialising on the Costa del Sol this summer.
Local residents are also concerned that many people are failing to comply with social- distancing measures when out enjoying themselves in Gibraltar in the evenings and that the rules are not being enforced.
