Athens:
A magnitude-5.6 earthquake has struck in the Mediterranean Sea south of the Greek island of Crete but no damage or casualties have been reported.
The Athens Geodynamics Institute says the earthquake occurred at 12:39 am local time on Sunday, some 50 kilometers (31 miles) off the south coast of Crete at a depth of 26 kilometers (16 miles).
A magnitude-5.9 quake had struck on Saturday evening, a little south of the current earthquake's spot and closer to the surface.
