Chanting slogans against the United States and President Barack Obama, the pro-government students, who called themselves Basij students, asked the United Nations to adopt a strong stance against the United States' recent nuclear threats against Iran.

Earlier this month, the Obama administration unveiled its long anticipated new nuclear strategy, promising to reduce the role of nuclear weapons in U.S. national security strategy while reaffirming extended deterrence commitments to its allies.

According to the strategy, known as Nuclear Posture Review, the U.S. will not use or threaten to use nuclear weapons against non-nuclear weapon countries that are members to the nuclear Non-Proliferation Treaty.

Iran believed the new strategy indicated that countries like Iran and the Democratic People's Republic of Korea that have violated or renounced the treaty will remain the potential targets of the U.S. nuclear forces.

Iranian Foreign Ministry Spokesman Ramin Mehman-Parast announced on April 11 that Tehran plans to lodge a formal complaint with the United Nations over U.S. threatening remarks against Iran.

The spokesman described U.S. President Barack Obama's remarks over a new U.S. nuclear strategy as "a threat to global security," saying "such remarks prove that the countries which possess nuclear arms are the greatest threat to the global security," according to Fars news agency.
