Four people were hurt Thursday when a car packed with explosives detonated near a military barracks in the southeastern port of Iskenderun, Turkey's Anadolu news agency said.
The blast was about 150 meters (500 feet) from the military installation.
Four people were hospitalized with injuries caused by shrapnel.
While authorities have not commented on the incident, Turkey's leading newspaper, Hurriyet, said on its Web site that the explosion was a terrorist attack.
The perpetrators planned to set off the explosives as a military convoy was due to pass, the daily said, adding that security forces are searching for the people behind the attack.
The outlawed Kurdish Workers Party, or PKK, has a history of targeting the security forces in Iskenderun, which lies near the border with strife-torn Syria.
Turkey has some 14 million Kurds, representing 18 percent of the total population, according to the CIA World Factbook.
In the PKK launched an armed struggle to win more rights for the Kurds, subject since the 1930s to a policy of assimilation.
More than 45,000 people have died in the conflict, many of them civilians. EFE
