Greek police say at least one of four Turkish men arrested during an anti-terror raid in Athens is wanted by Turkish authorities on charges of participating in a terrorist organization.

The four, aged from 25 to 49, were to appear in court later Tuesday on terrorism-related charges. They were arrested Monday after a raid on an Athens apartment uncovered weapons, explosives, detonators and berets bearing the emblem of the Revolutionary People's Liberation Party-Front, or DHKP-C.

Originally founded in the late 1970s as Dev Sol, the Marxist-Leninist DHKP-C has been deemed a terrorist organization by Turkey, the United States and the European Union. It is believed responsible for a string of assassinations and bombings in Turkey, including a suicide bomb attack on the U.S. Embassy in Ankara last year.
