Iran's Revolutionary Guard Issues 'Deadly' Warning After Alleged Missile Tests

IRGC Issues Stern Warning Amid Rising Tensions

Iran's Islamic Revolutionary Guard Corps (IRGC) issued a stark warning on Sunday, September 21, 2025, vowing a 'deadly' and 'crushing and decisive' response to any miscalculation or aggression by its adversaries. This declaration followed widespread reports of mysterious nighttime military activity and alleged missile tests near the capital, Tehran, days earlier. The IRGC's statement explicitly targeted 'the fake and criminal Zionist regime' and the United States, emphasizing that 'If the enemy makes mistakes, Iran's hand will be on top.' The Guard asserted its intent to 'seize the initiative on the battlefield and respond in a deadly and instructive way once again'.

Alleged Missile Tests Spark Speculation

On Thursday evening, September 18, 2025, eyewitnesses and social media users reported seeing glowing objects and smoke trails arcing across the night sky over Tehran and several northeastern cities, including Gorgan, Sari, and Semnan. These sightings fueled speculation about recent military exercises. A senior lawmaker, Mohsen Zanganeh, claimed that Iran had successfully tested one of its most advanced intercontinental ballistic missiles (ICBMs) 'two nights ago,' stating it was a missile that 'had not yet been tried, and it succeeded.' While a local official confirmed missile system tests near Tehran, Iran's state-aligned Fars news agency sought to downplay the incident, describing it as 'internal system tests' rather than weapons trials. Reports from Iran International also indicated that air defense systems were activated late Saturday in western Tehran.

Context of Heightened Regional Volatility

The IRGC's warning coincides with the re-imposition of United Nations sanctions, which took effect just two days prior to the Guard's statement. In a related development, Iran's Supreme National Security Council (SNSC) announced its decision to 'effectively suspend the path of cooperation' with the International Atomic Energy Agency (IAEA) in response to these sanctions. These events unfold against a backdrop of significantly heightened regional tensions, particularly following a '12-day war' with Israel in June. During that conflict, Israel reportedly targeted and damaged parts of Iran's missile and nuclear capabilities, with the United States also striking nuclear facilities. Iran retaliated with missile barrages, further escalating hostilities. Iranian officials have consistently maintained that their military capabilities, including missile power, are solely for defensive purposes and are not negotiable.

Iran's Stance on Deterrence and Self-Reliance

The IRGC's recent statement, issued at the beginning of 'Sacred Defense Week'—a commemoration of the Iran-Iraq war—underscored Iran's commitment to strengthening its defense. The Guard emphasized that Iran's deterrence strategy relies on 'permanent readiness, innovative strategy, and continuous development of advanced defense technologies.' It highlighted that despite international sanctions and pressure, Iran's armed forces have achieved a high level of self-sufficiency and resilience. President Masoud Pezeshkian has also publicly affirmed Iran's resolve to withstand international sanctions and any potential foreign attacks, reinforcing the nation's defiant posture.
