Iran condemned as "not fair" Tuesday a report by the UN nuclear watchdog on traces of nuclear material found at three undeclared sites.

The comments came with talks deadlocked since March on reviving a 2015 nuclear agreement between Tehran and world powers.

"The situation at the Zaporizhzhia Nuclear Power Station in Ukraine is not sustainable, which could prove dangerous," warned Rafael Grossi, director general of the International Atomic Energy Agency.
The Russians took over the same power plant in early March, and Grossi now warns that his organization is unsuccessfully trying to access the largest nuclear plant in Europe.

Five months after they were suspended, international talks on Iran's nuclear programme will restart on Monday in Vienna with analysts foreseeing major obstacles to any speedy resumption of the 2015 nuclear deal.

The U.N. nuclear watchdog chief announced on Feb. 21 a "temporary solution" to allow Iranian facility inspections to continue after days of talks with officials, giving some much needed breathing space for diplomatic negotiations.
