An explosion in a trash container in the southern Mediterranean city of Mersin injured one person on Wednesday, and police detained a man in connection with the blast, the Anatolia news agency reported.
The reason for the explosion, the sixth to cause injuries in Turkey in a week, was not yet known. The injured person was taken to a nearby hospital for treatment, Anatolia said. No information was given about the suspect.
The blast came on a day that saw hundreds of flag-waving Turks march to denounce this week's five previous bomb attacks by an outlawed Kurdish militant group that killed three people and wounded dozens of others in tourist resorts and in Istanbul.
Protesters shouted anti-Kurdish rebel slogans during a march in the Mediterranean resort town of Marmaris, the scene of a bus bombing Sunday which injured 10 Britons and 11 Turks. On Monday, another bomb attack killed three people and injured dozens more, including several tourists, in the resort city of Antalya.
The Kurdistan Freedom Falcons, a Kurdish militant group, claimed responsibility for both attacks as well as for another bomb blast in Istanbul that injured six people on Sunday.
The group warned it would turn Turkey "into hell" and urged tourists to avoid the country.
The Falcons are believed to be an offshoot of the much larger Kurdistan Workers Party, or PKK, which has been fighting for autonomy in the country's Kurdish-dominated southeast since 1984. The conflict has killed more than 37,000 people so far, and the PKK is listed as a terrorist organization by the United States and the European Union.
The protest on Wednesday in Marmaris took place as residents gathered in downtown areas to attend military celebrations to mark the anniversary of a 1922 victory over the invading forces of France, Britain, Italy and Greece.
Following the recent surge of Kurdish rebel violence, police and paramilitary police took tight security measures for celebrations for "Victory Day" across the country.
