A series of earthquakes near Santorini, Greece has prompted tourists to flee the area and the country to declare a state of emergency.

More than 11,000 people have already left the island of Santorini following a series of tremors in recent days.

Greek authorities are monitoring increased seismic activity on the island of Santorini, Prime Minister Kyriakos Mitsotakis said on Friday, urging the public to remain calm and follow the advice of the civil protection service.
