The U.N. Panel of Experts responsible for monitoring the Security Council's sanctions on Iran reports that Tehran's illicit procurement efforts for its nuclear and missile programs may have slowed. It is not clear, however, whether this decrease is due to better concealment by Iran, according to the Panel. The Panel's report details Iran's use of its petrochemical industry as a cover for the procurement of valves for the Arak heavy water reactor, and warns countries that Iran is using freight-forwarding firms to mask the destination and end-use of shipments. The report also cites a 2013 directive by Iran’s Supreme National Security Council ordering Iranian banks and state firms to set-up front companies for Khatam al-Anbiya Construction Company in an effort to avoid U.N. sanctions. Khatam al-Anbiya has been sanctioned by the United Nations for supporting Iran's nuclear program.
