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 10,000 people have left on ferries and planes in recent days as hundreds of small quakes were registered in the surrounding sea,

Emergency services were deployed in readiness and schools were closed after more than 200 temblors struck in the Aegean, near Santorini, within 48 hours.

Mitsotakis's remarks come as many people in Santorini spent Sunday night outdoors, amid fears of potential damages 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.
