A small bomb exploded overnight outside an election bureau of Turkey's ruling party in Istanbul, causing damage but no casualties, Anatolia news agency reported Wednesday.
Turkey holds legislative elections on Sunday.
The bomb, left in a flower pot outside the election bureau of the Justice and Development Party (AKP) in Bahcelieveler district, shattered the windows of the building.
There was no immediate word on who might be behind the blast.
Last Sunday, two small bombs designed to make loud noise rather than kill went off outside election offices of the AKP and the far-right Nationalist Action Party in the western city of Izmir, causing material damage.
