Emergency alert sirens to be tested in Greece as of 11:00 am on Monday; schedule

Greece's Civil Defense will test its air raid system throughout the country between 11:00 am and 11:35 am on Monday, it was announced on Sunday.

The civil defense sirens will be activated in the framework of the Greek military exercise 'Parmenion-23'.

Testing the system will be as follows:

- 11:00, air raid sirens tested, over 60 seconds (an intermittent sound of varying volume)

- 11:05, air raid conclusion sirens, over 60 seconds (a consistent sound of the same volume)

- 11:30, air raid warning for chemical warfare threat (chemical, biological, radiological, and nuclear incidents), over 120 seconds (intermittent sound of varying volume)

- 11:35, air raid conclusion sirens, over 60 seconds (a consistent sound of the same volume)

While air raid sirens are heard, all churches in Greece will be ringing their bells in a series of short rings at a fast tempo, over 3 minutes.
