New Delhi, Sep 17 (ANI): Iran's Supreme Leader Ayatollah Sayyid Ali Khamenei said that Iran would react strongly to any "wrong move" by the United States over nuclear deal. The supreme leader warned US after President Donald Trump accused Iran of violating the "spirit" of the agreement. The supreme leader said the Iran is standing firm on the deal but will react strongly if any wrong move regarding the nuclear accord will happen. The leader further added that US attitude towards negotiations and their outcome is completely unjust and amounts to bullying. The United States imposed unilateral sanctions after saying the missile tests violated a U.N. resolution, which endorsed the nuclear deal and called upon Tehran not to undertake activities related to ballistic missiles capable of delivering nuclear weapons, including launches using such technology.
