Israel’s defense minister claimed Thursday that Iran could have enough enriched uranium for five nuclear weapons, and warned Tehran that proceeding to weapons-grade enrichment could “ignite the region.” His remarks echoed international concerns, which have mounted over the past months, on Tehran enriching uranium closer than ever to weapons-grade levels. Experts have said that Tehran has enough fuel to build “several” atomic bombs if it chooses. “Make no mistake, Iran will not be satisfied by a single nuclear bomb,” Israeli Defense Minister Yoav Gallant said Thursday during a visit to Athens. Uranium enriched for use in nuclear power plants is normally below 20%, while 90% enrichment is considered to be weapons grade. “So far, Iran has gained material enriched to 20% and 60% for five nuclear weapons," Gallant said. "Iranian progress, enrichment to 90%, would be a grave mistake on Iran’s part and could ignite the region.” The International Atomic Energy Agency said in March it would restart inspections and camera-monitoring at some Iranian nuclear facilities after it reported that particles of highly enriched uranium were found at an underground nuclear site.
