Iran’s top national security official has warned US President Donald Trump that any American interference in Iran’s internal affairs would destroy US interests in the region.

Iran’s top security official says Tehran will only engage in genuine talks with the United States without any unconditional concession.

Iran’s Supreme National Security Council Secretary Ali Larijani says external economic pressure will fail to erode the country’s resilience.

Iran’s top security official says resistance is always steadfast and victorious.
