Those arrested are all Syrians with fake passports and include a man described as the ringleader and named as 18-year-old Abdulaziz Amin Mojbil, the agency said. The arrests took place in early morning raids in Istanbul's Esenyurt district.
Turkey earlier this week already arrested an alleged IS member suspected of planning a suicide attack on the US consulate in Istanbul.
Intelligence about the planned attack prompted the partial closure of the consulate on December 9, when it offered only limited services with a scaled-down staffing.
