Iran has rejected the latest European proposals for resolving concerns over the country's nuclear programme, BBC News reports.
Tehran has threatened to resume nuclear activities next week that have been suspended since November 2004.
According to AP, Foreign Ministry spokesman Hamid Reza Asefi said the government would send its official rejection to the Europeans later Saturday or Sunday.
"The European proposals are unacceptable ... the package is against the spirit of the Nuclear Nonproliferation Treaty and against the provisions of the Paris agreement," he said on state radio. "The proposals do not meet Iran's minimum expectations."
The U.N. nuclear watchdog, the International Atomic Energy Agency, announced it would hold an emergency meeting Tuesday to formally warn Iran not to resume uranium enrichment at its Uranium Conversion Facility in Isfahan. The IAEA board could refer Iran to the U.N. Security Council for consideration of sanctions.
The EU nations also say Iran must "stop construction of its heavy water research reactor at Arak." Nuclear experts consider heavy water reactors a danger because they use higher-grade plutonium suitable for weapons use. They say the reactor at the Iranian city of Arak can yield enough plutonium from spent fuel to make one atomic bomb a year
