Turkey's state-run news agency says police have detained 11 people in a new security sweep in Istanbul against suspected Islamic State militants.

The Anadolu Agency says the suspects, including seven foreign nationals, were detained Thursday during simultaneous raids on some 20 addresses in the city.

The report said the suspects had arrived in Turkey to join the IS group. There was no information on their nationalities.

Turkey has detained dozens of IS suspects in recent weeks, including some 20 in or near the city of Antalya, which will be hosting U.S. President Barack Obama and other G-20 leaders at a summit meeting Sunday and Monday.
