The first two ATMs hit were located in front of a supermarket on Marathon Avenue.
The blast, which occurred at 4:10 am, caused damage to both the ATM and the supermarket window glass.
The explosion at the third ATM, which was located at the 40th km of the Athens-Corinth National Highway, at the Megara, in a kiosk, happened a little later at 4:20 am.
So far it has yet to be determined whether the culprits took the cash from the ATMs.
Police are conducting investigations to detect the culprits.
