ATHENS — Greece's back-and-forth with tough and lenient COVID-19 health restrictions had been tightened on the island of Zakynthos and the city of Hania on Crete because of rising cases as vaccinations lag and people violate measures.

Those two areas were hit with a night curfew and music ban, the same tactics that were used briefly on the wild party island of Mykonos before the New Democracy government relented when businesses started screaming.

The restrictions on Zakynthos and in Hania will run until Aug. 13, based on a recommendation from the government's advisory panel of doctors and scientists after reviewing epidemiological data, said the Reuters news agency.

"We call on the residents and visitors in these areas to fully comply with the measures to limit the spread of the virus," the Civil Protection agency said as COVID keeps spreading on islands where tourism workers don't have to be vaccinated so far.
