Repeated earthquakes are rattling Greece’s volcanic island of Santorini. Scientists say the quakes aren't related to a slight increase in volcanic activity that has also been registered recently.

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.

Thousands of people evacuated Santorini after a series of earthquakes in recent days hit the picturesque Greek island with fears of additional tremors.
