A state of emergency has been declared in Santorini after the strongest earthquake was recorded in days of near-constant tremors, which have almost emptied the famous Greek tourist haven of visitors and residents.

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.
