The United States, Britain, France and Germany are accusing Iran of violating U.N. sanctions prohibiting any launches using ballistic missile technology, as well as an arms embargo.
U.S. Ambassador Susan Rice said the four countries reported the ballistic missile violation to the Security Council committee monitoring sanctions against Iran.
She spoke after a Security Council briefing by Colombia's U.N. Ambassador Nestor Osorio, who heads the sanctions committee and reported on several alleged sanctions violations.
Osorio said the committee is examining allegations by four U.N. members that Tehran violated the ban on using missile technology.
Britain's U.N. Ambassador Mark Lyall Grant said the violation occurred when Iran launched the Rasad 1 satellite in June,, "which is dependent on ballistic missile technology."
