An adviser to Iran's Supreme Leader Ayatollah Ali Khamenei has reignited concerns over the country's nuclear ambitions, particularly in light of escalating tensions with Israel.
Kamal Kharrazi, the adviser, hinted at a shift in Iran's nuclear doctrine if its existence is perceived to be under threat by Israel.
Kharrazi said, "We have no decision to build a nuclear bomb, but should Iran's existence be threatened, there will be no choice but to change our military doctrine.
"Tensions between Iran and Israel reached a tipping point when the former launched a barrage of explosive drones and missiles directly targeting Israeli territory, in response to the bombing of Iran's embassy in Syria's capital Damascus earlier in April.
