Iran summoned diplomats representing the United Kingdom, France and Germany on Thursday in protest over a UN Security Council meeting on Tehran's nuclear programme, a foreign ministry statement said.
There was "no technical or legal justification" for the meeting, the statement said, calling it "provocative and political, in line with the unilateral and nervous approach of the United States".
The meeting on Iran's programme on Wednesday saw the US mission accuse Iran of "brazen behaviour" related to its nuclear programme.
Several Council members had requested the meeting over the latest report from the UN's International Atomic Energy Agency.
The report said Iran had significantly increased its stockpile of highly enriched uranium to 60 percent purity -- close to the 90 percent needed for an atomic bomb.
