Israeli Prime Minister Benjamin Netanyahu on Tuesday said Israel and the US struck Iran as Tehran had restarted its nuclear programme and it would have gone “immune within months”. Netanyahu said an attack against Iran was urgently needed because Tehran was building new underground sites to shield its missile and nuclear programmes from attacks.“They started building new sites, new places, underground bunkers that would make their ballistic missile programme and their atomic bomb programme immune within months. If no action was taken now, no action could be taken in the future,” he said. “The reason that we had to act now is that after we hit their nuclear sites and their ballistic missile programme, they started building new sites.”
