Iran has accumulated a vast amount of enriched uranium, which is "very, very close" to weapon grade, International Atomic Energy Agency chief Rafael Grossi told NDTV during the ongoing World Economic Forum Summit in Davos.

India's nuclear reactors are "absolutely safe" as it applies the highest levels of safety standards to its civil nuclear programme, the chief of global nuclear watchdog International Atomic Energy Agency (IAEA) has told NDTV.

Europe's largest and now Russian-occupied Zaporizhzhia nuclear power plant (ZNPP) in conflict-hit Ukraine had been minutes or hours away "a few times" from a nuclear catastrophe, the head of the IAEA told NDTV in Davos.
