Iranian Parliament Speaker Mohammad Bagher Ghalibaf has warned the United States that Tehran would respond swiftly if Washington makes any miscalculations or engages in acts of war.

“Do not make mistakes in your calculations, and if you err, Iran will not hesitate to respond with swift and unexpected defence. This time, the Islamic Republic of Iran’s armed forces will determine the geography of the conflict,” Ghalibaf said, The Caspian Post reports, citing Al Jazeera.

He made the remarks during the unveiling of a new missile city in Iran, describing the facility as a clear message to the country’s adversaries.

Ghalibaf said Iran would continue strengthening its defence capabilities despite the threat of war.

“The children of Iran do not neglect improving their defence capabilities, even under the fire of war,” he said.

He added that the unveiling of the new missile city belonging to the Islamic Revolutionary Guard Corps (IRGC) Aerospace Force demonstrated the Iranian people's determination to protect the country's independence, security, and territorial integrity.
