Suspects that carried out a terrorist attack against the police headquarters in the Turkish capital of Ankara three days ago could have links to foreign countries, daily Today\'s Zaman reported on Monday. Muharrem Karatas and Serdar Polat, members of the far-left Revolutionary People\'s Liberation Party/Front, illegally entered Turkey from Greece and Syria, the report said, adding that one of them was shot dead and the other wounded by the police. The suspects received orders in their camps in Greece and Syria a week before their operation, the report said, citing security sources. Karatas also carried out a rocket attack against the headquarters of the ruling Justice and Development Party in March, Interior Minister Muammer Guler said on Saturday. The rocket attack against the police headquarters on Friday night in Ankara caused no casualties but damaged the building.
