A strong earthquake has shaken the Greek capital of Athens, knocking out phone networks and power in parts of the city.
The 5.1 magnitude earthquake had an epicentre about 22km north-west of Athens.
Athenians ran out into the streets as the city shook for 15 seconds.
There were no reports of serious injuries, but several aftershocks have been felt and two buildings have collapsed.
The strongest aftershock had a magnitude of 4.3, almost an hour after the initial quake hit at 2:13 PM. Seismologists warn there could be more.
