The meeting of the International Atomic Energy Agency (IAEA)'s board of governors, which follows a US request, would be held "on 10 July at 14:30," an IAEA spokesman said.

Earlier, the US mission in Vienna said in a statement that the American Ambassador to International Organizations Jackie Wolcott had requested the special meeting to discuss Iran's breach of the amount of enriched uranium it could stockpile.

The IAEA confirmed earlier this week that Iran had breached the limit of 300kg for stockpiles of enriched uranium as stipulated under the 2015 Joint Comprehensive Plan of Action (JCPOA).

The US statement described the news of the breach as "concerning".

"The international community must hold Iran's regime accountable," the statement added.

Iran has said that as of Sunday it will begin breaking another key limit set in the JCPOA, which restricts the enrichment level of its uranium stockpile to 3.67 percent.
