The fragile ceasefire between the United States and Iran is approaching a critical breaking point, with Tehran warning that continued Israeli strikes in Lebanon could collapse the agreement within hours. Mahdi Mohammadi, an Iranian national security adviser, issued a stark message, stating that only “limited hours remain” to preserve the ceasefire. He warned that unless Israel is fully restrained in Lebanon, there would be “no ceasefire or negotiations,” adding that missiles are already prepared for launch, a clear signal of imminent retaliatory options.
