Iran has given a firm commitment to cooperate with a U.N. nuclear watchdog investigation into suspected atomic bomb research, the head of the agency said after what he described as a "useful" visit to Tehran on Sunday. Yukiya Amano made the trip ahead of an Aug. 25 deadline for Iran to provide information relevant to the International Atomic Energy Agency's long-running inquiry into what it calls the possible military dimensions of the country's nuclear program.
The issue is closely tied to Iran's negotiations with six world powers aimed at ending a decade-old standoff over its atomic activities and dispelling fears of a new Middle East war. Iran denies its program has any military objectives.
"This has been a short visit, but a useful one," Amano said in the Iranian capital after talks with President Hassan Rouhani and other senior Iranian officials, according to a statement issued by the IAEA in Vienna.
Since Rouhani was elected in mid-2013, Tehran has promised to work with the U.N. agency to clear up the suspicions about its nuclear aspirations. After meeting Amano, Rouhani said on his English-language Twitter account that Iran was "determined to forge accord with the IAEA in the shortest possible time span. God willing, it can be done in less than a year."
