A series of earthquakes near the Greek island of Santorini have led authorities to shut down schools, dispatch rescue teams with sniffer dogs and sent instructions to residents including a request to drain their swimming pools.

The Greek island of Santorini is being rattled by dozens of tremors, prompting authorities to close schools and airlines to announce additional flights on Monday to help people leave the popular tourist destination.

Mitsotakis's remarks come as many people in Santorini spent Sunday night outdoors, amid fears of potential damage to buildings during the quakes. Some focal points of the tremors have been recorded at a depth of just 2km (1.2miles) below the surface.
