The head of the United Nations nuclear watchdog has said Iran has agreed to answer outstanding concerns about its nuclear programme and accepted tougher inspections of sites.
Speaking on a visit to Tehran, Mr Mohamed ElBaredei said that despite agreeing to let inspectors visit facilities without notice, Iranian officials still had misgivings about signing the Additional Protocol of the nuclear Non-Proliferation Treaty.
His visit comes just two weeks before an October 31st UN deadline for Iran to disprove US-led claims it has a secret atomic weapons programme. Failure to do so could see Iran's case referred to the UN Security Council in November.
Mr ElBaradei arrived in Tehran overnight warning that Iran had still not provided the International Atomic Energy Agency (IAEA) with the full disclosure it was seeking.
He said Iran's Supreme National Security Council chief Hassan Rohani had "expressed Iran's willingness to sign the Additional Protocol" on tougher inspections but still had some "apprehensions" about how the protocol would work.
