A senior Iranian official has called for curbing the promotion of Wahhabism in the West and the support some regional countries provide for terrorist groups. “Western governments should not allow extremist groups to operate in their countries with the help of certain Middle East states,” said the head of Iran’s Strategic Council on Foreign Relations, Kamal Kharrazi. He made the remarks in a meeting with a British parliamentary delegation, headed by Chairman of the UK Parliament’s Foreign Affairs Committee Crispin Blunt, in Tehran on Saturday, Press TV reported. Kharrazi said western countries have closed their eyes to acts of terror, adding that such activities have created instability in the Middle East and also affected other parts of the world, including Europe. The British official said his visit to Iran and some other regional countries is aimed at finding ways to deal with the so-called Islamic State militant group.
