Turkey's state-run news agency says police have detained some 20 people suspected of links to the Islamic State group ahead of a G-20 summit near the Mediterranean coastal city of Antalya.

Anadolu Agency says the suspects, including two Russian nationals, were detained Friday in raids in and around Antalya, which will be hosting U.S. President Barack Obama and other G-20 leaders later this month.

Massive suicide bombings in the Syrian border town of Suruc and in the capital Ankara — blamed on Islamic State militants — have killed some 130 people since July.

Last month, Turkey claimed it struck a major blow to an IS cell in a raid in the southeastern city of Diyarbakir, in which seven militants reportedly were killed.
