Turkey arrests 13 suspected Islamic extremists

Several of those arrested by anti-terrorist intelligence agents were suspected of having undergone training in overseas camps.

Turkey has introduced unprecedented security measures ahead of the June 28-29 summit to protect NATO leaders, including US President George W. Bush, and carried out a number of arrests among Islamists, as well as Kurdish and left-wing extremists.

On Tuesday, about 30 people employed by Kurdish cultural and press organizations, including the news agency Dicle, were arrested here.

Most of them were later released but two of them were to be tried by a state security court, said Dicle journalist Gulbahar Salik.
