Some 15 people were injured in the blast which disturbed the peace of the resort of Kemer explosion in the Mediterranean resort of Kemer in southern Turkey on Sunday morning, according to several media reports.

Among the injured were four Swedes.

The four Swedes affected by the blast travelled to Turkey with the Turkietresor tour agency.

According to the agency’s CEO Marie Andersson, the four were near the explosion on the beach.

“We sent them to the local hospital immediately, with one couple discharged immediately. One of the people in the other couple complained of pain in the ear passage, because there was a loud explosion, and so we transported them to a larger hospital with specialist care inside the region’s capital city of Antalya.”

Andersson told news agency TT that she has not received any conclusive reports on the nature of the explosion.

“But we do not believe that there was a bomb, the explosion was instead on a smaller scale.”
