The latest report by the U.N. nuclear watchdog underscored Iran's refusal to comply with international requirements needed to allow constructive talks on its nuclear program, Reuters quoted the White House as saying today. "This latest IAEA report clearly shows Iran's continued failure to comply with its international obligations and its sustained lack of cooperation with the IAEA," White House National Security Council spokesman Mike Hammer said. He was referring to a confidential report obtained by Reuters that said Iran has been preparing extra equipment for enriching uranium to higher levels. Such a move could increase tensions with the West over its atomic work. President Barack Obama's administration is leading a push for new U.N. Security Council sanctions against Iran.
