The US is lobbying other countries on the UN nuclear watchdog’s board of governors to back a draft resolution demanding that Iran tell the agency what happened to its bombed nuclear sites and the enriched uranium stored at these locations. The US-drafted text, seen by Reuters on Sunday and circulated ahead of this week’s quarterly meeting of the 35-nation board, risks complicating talks between Washington and Tehran.The US draft says Iran must “provide the Agency with precise information on nuclear material accountancy and safeguarded nuclear facilities in Iran” and grant “all access it requires to verify this information.” Both steps are described as “essential and urgent” and must be taken “without delay”. The text stops short of referring Iran to the UN security council, a move some diplomats had said was under consideration. While circulating a draft does not guarantee it will be submitted to the board, which would then vote on it, it signals an intention to do so. Current US-Iran talks aim to extend the ceasefire and pave the way for broader negotiations, including nuclear programme.Catch all LIVE updates on the US-Iran conflict here.
