Athens, Greece - Seismologists in Greece say a 5.1 magnitude earthquake has rattled the south of the country, but there have been no reports from authorities of damage or injury.

Athens Geodynamic Institute, a state earthquake monitoring agency, said the undersea quake occurred at 11:37 a.m. (0937GMT), 120 kilometres (75 miles) south of Athens, near the island of Milos. It struck at a depth of 103 kilometres (64 miles).

Municipal authorities on the Aegean Sea island say the quake was barely felt in the main town of Plaka.
