At least four people have died, and 71 have been injured in the suspected bomb attack in central Antalya on Monday afternoon, said the Turkish DHA news agency citing police sources.
"The victims are Dmitry Maksimov, 30, who was wounded in the arm and is suffering from a severe hemorrhage, and Olga Prevezentseva, 26, who sustained shellshock," Sergei Alifanov said.
The victims have been taken to a private clinic in Antalya where Russian diplomats are now heading, Alifanov said.
Alifanov said an explosive device was thought to have been planted in a kiosk selling bread. He added that the explosion hit the city center at about 4:45 p.m. local time (1:45 p.m. GMT).
"The explosion took place at a busy crossing in central Antalya," the diplomat said. "According to police data, three people died on the site of the explosion and over twenty people received injuries of varying severity."
Turkish media said the victims included four Israelis and a Jordanian, who had been taken to hospital. Other reports said one German was also among the victims.
Two bodies have been identified as Turkish citizens, a police officer and a woman, DHA said.
According to eyewitnesses, the explosion, which occurred in a popular tourist location, was so powerful that it demolished nearby cars, and smashed windows in neighboring buildings.
Alifanov said the blast went off about one kilometer away from the Russian diplomatic mission, and he himself was 80 meters away from the site.
"I was driving and found myself 80 meters from the site of the incident," he said.
The area has been cordoned off by police, and all the cars are being evacuated, local television said.
Earlier Monday, explosions rocked the cities of Istanbul and Marmaris, injuring 21 people, including 10 British tourists.
