A small explosive device detonated outside a building housing Eurobank offices in central Athens on Wednesday, damaging its entrance and shattering windows, police said.There were no injuries, police said.
Officials said the explosion followed an anonymous warning call to a private Greek television station and police were able to evacuate the area before the bomb detonated.
A police statement said the device was left in a bag outside the entrance to the bank, which is close to two busy avenues.
No group claimed responsibility for the attack. Similar bombings in the past have been claimed by extreme left or anarchist groups.
