|Local and foreign tourists put flowers at the bombing scene in Kusadasi|
The provincial governor, Mustafa Malay, said on Sunday that the explosives were placed under the seat of a mini-van in the resort of Kusadasi, and set-off by a timer or remote control.
Five people were killed and at least a dozen injured, including British and Irish tourists.
Officials have not named any suspects, but the British Ambassador to Turkey, Peter Westmacott, was quoted as saying officials suspected the outlawed Kurdistan Workers Party, which he called a terrorist group.
The group issued statements denying any responsibility, and said it was not connected with another Kurdish group, Kurdistan Freedom Falcons, that claimed responsibility for a bombing at another tourist spot last Sunday.
About 37,000 people have died in Kurdish-related violence in Turkey since 1984.
