City mayor Menderes Turel told the broadcaster NTV that “10 to 12 people were slightly injured by flying glass” in the explosion at the Antalya Chamber of Commerce and Industry building. The blast occurred at 8.50am.
Turel told CNN Turk channel the blast was being investigated and it was “too early” to make assumptions as to the cause.
“The blast may not be a terror attack… we must wait for official information,” Turel said.
Antalya Chamber of Trade and Industry head Davut Cetin also told CNN Turk there were no fatalities in the explosion.
Over the past year, Turkey has suffered a series of attacks blamed on the Islamic State jihadist group and Kurdish militants.
TV images showed a wrecked, burned-out car and smashed glass nearby. At least four cars nearby were also damaged, Dogan news agency said.
An eyewitness who was at the building told CNN Turk the blast smashed windows and left people bloodied, while a reporter for the Dogan news agency said one vehicle was blown apart.
Antalya is a major tourist resort on Turkey‘s Mediterranean coast. In August, two rockets hit a commercial facility near a resort town in the province, but caused no casualties.
It was not immediately clear who was responsible for that attack, but Kurdish and far-left militants have staged similar attacks, mostly against the security forces, in the past.
The incident occurred 11 days after three rockets hit a roadside fishmonger in the popular tourist region, but without causing casualties.
