Hundreds more people were expected to leave Greece's Santorini island on Wednesday as tremors shook the popular summer tourist destination for a sixth day. About 6,000 people have left on ferries and planes in recent days as hundreds of small quakes were registered in the surounding sea,

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.

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.
