The suspects were among 28 people rounded up in simultaneous raids Thursday by anti-terror police and the national intelligence agency in the western province of Eskisehir.

Last month, a Turkish newspaper reported that Ankara had received US intelligence that al-Qaeda militants could be plotting attacks on foreign targets in Turkey.
A Turkish cell of al-Qaeda was held responsible for truck bombs against two synagogues, the British consulate and a British bank in Istanbul in 2003, which killed 63 people and left hundreds injured.
Seven men were jailed for life in 2007 over the bombings, among them a Syrian national who masterminded and financed the attacks.
In January, a suspected al-Qaeda militant was killed and three others captured in a shootout with the police in Istanbul after the group attempted to rob a post office.
