United Nations ( CNN ) -- Iran continues to evade and violate a U.N.-imposed arms embargo , according to a sanctions committee report released Friday to the Security Council . Ambassador Tsuneo Nishida of Japan , who is the chairman of the committee , told the Security Council that within the past 90 days , the committee has been investigating two separate incidents of reported Iranian violations . One violation , he said , involved a report by a member country that from one of its ports , it `` inspected and seized 13 shipping containers of illegal arms reportedly originating from Iran . '' The committee said it would issue a more comprehensive report of the results in the near future . The other report of violations involved a separate member country whose customs and border authorities seized a container onboard a ship which originated from Iran and was destined for Syria . It contained `` a high-potential explosive known as 'T4 ' or 'RDX'. `` Susan Rice , the U.S . Ambassador to the United Nations , reacted to the report saying , `` Unfortunately , when it comes to Iran 's actions , not much has changed since we last met . Iran continues to violate its obligations '' to the Security Council . In 2007 , Security Council Resolution 1747 imposed a ban on the export and procurement of all arms and related material from Iran .
Committee chairman says panel is looking at two separate reports . Committee says it has 13 reports of illegal arms . Separate report says high explosives were bound for Syria .
