The Israeli prime minister, Benjamin Netanyahu has described Iran as "the greatest threat to world peace."
His comments follow a report from the UN nuclear watchdog which says Tehran has doubled its capacity to enrich uranium, which could be used to make a nuclear bomb.
Meanwhile, Ayatollah Khamenei, Iran's supreme leader, has insisted his country is not developing nuclear weapons.
Despite this, speculation about the possibility of conflict with Iran is a hot topic of discussion in Israel.
