Iran has been critical of IAEA after Israel's and the US's attack on Iranian nuclear facilities earlier in the summer and at the end of June, the country's parliament decided to discontinue cooperation with the nuclear energy agency.
Iran's decision to temporarily stop cooperation with IAEA is met with concern by the UN.
We have seen the official decision, which is undoubtedly worrying, says the spokesperson for the UN Secretary-General António Guterres.
The Secretary-General has been very clear in his call to Iran to cooperate with IAEA, and honestly, for all countries to cooperate with IAEA in nuclear energy matters, says spokesperson Stephane Dujarric.
