The world body, is meeting at the request of France and Britain after they accused Iran of test-firing a medium-range missile at the weekend.
The United States has said the missile launch on Saturday was a violation of a UN resolution that endorses the 2015 Iran nuclear deal from which Washington has withdrawn.
France and Britan have also expressed concern over the missile test-firing by Iran.
The UN resolution that endorse the 2015 nuclear deal calls on Iran to refrain from testing missiles capable of carrying a nuclear weapon.
Iran has long maintained that its missile program is defensive in nature and not aimed at ensuring the delivery of a nuclear weapon, a stance supported by Russia at the Security Council.>
