VIENNA: The UN nuclear watchdog said it had a “constructive exchange” with Iran this week but there was no sign of a breakthrough on aspects of its nuclear programme that the agency says Tehran has failed to fully address.

The International Atomic Energy Agency (IAEA) is investigating Iran’s nuclear programme in parallel to talks between Tehran and six world powers that aim to broker a deal by the end of June to scale down the programme in exchange for sanctions relief.

In any final deal, the IAEA would play a major role in monitoring Iran’s compliance.

The IAEA said in March it expected progress with Iran this month on outstanding issues related to the nature of neutron calculations and alleged experiments on explosives that could be used to develop an atomic device.
