Washington, 30 April (WashingtonTV)—Iran remains the “most active state sponsor of terrorism” in the world, the US State Department charged on Thursday. Iran, along with Cuba, Sudan and Syria, were designated as state sponsors of terrorism, in the State Department’s report for 2008. All four countries were listed in previous reports. The designation imposes a ban on arms-related exports and sales, controls over exports of dual-use items, prohibitions on economic assistance and other miscellaneous restrictions.
