Sirens to sound between 11 and 11.05 a.m. on Wednesday

Civil defense sirens are scheduled to go off across Greece Wednesday as part of the annual military and public defense exercise dubbed Parmenion, after the Macedonian general of Philip II and Alexander the Great.

The air-raid sirens will sound at 60-second intervals, starting at 11 a.m. and lasting until 11.05 a.m.

The public is advised that the air-raid drill is simply a preparedness exercise and should not cause any alarm.
