Churchgoers have been instructed to wear double masks during Holy Week services in Greece.
The announcement was made last week by Deputy Civil Protection Minister Nikos Hardalias.
Last year, Orthodox Easter services were cancelled.
Moreover, indoor attendance will be limited to one person per 25 square meters, a maximum of 100 people.
Self-tests are obligatory for priests, nuns and other members who will be inside the church.
The ratio outside churches during services has been set at one person per 10 square meters.
