TEHRAN (AFP) - Iran offered on Monday to grant the UN nuclear watchdog "full supervision" of its atomic programme for five years if sanctions are lifted, as the EU insisted Tehran first meet its international obligations. "We have proposed that the agency keep Iran 's activities and nuclear programme under full supervision for five years, providing the sanctions are lifted," Iranian nuclear chief Fereydoun Abbasi Davani told ISNA news agency. He neither said when the offer was made to the International Atomic Energy Agency (IAEA) nor what he meant by "full supervision." Iran is targeted by four sets of UN Security Council sanctions over its refusal to suspend uranium enrichment amid fears in the West that it seeks to build a nuclear bomb - a charge it vehemently denies. Much of Iran 's nuclear activities are already under the control of the IAEA, including uranium enrichment - a process which can produce the fuel for a nuclear reactor and also the fissile material for an atomic warhead.
