The ambassador to France says terrorism cannot be categorized into “good and bad,” urging the countries that provide political and financial aid to terrorist groups to cut their support and close their borders to terrorists. Ali Ahani made the remarks in a meeting on terrorism in Paris, ISNA reported on Saturday. He said, “Terrorism is rooted in undemocratic systems in the world, military intervention and double standards on terrorism,” adding that regional cooperation is essential to deal with the issue.
