A senior Iranian security official has warned former U.S. President Donald Trump not to interfere in Iran’s ongoing protests. Speaking to local media on Friday, the official said any U.S. involvement in Iran’s internal affairs would destabilize the entire region and would be met with a strong response. The warning followed Trump’s post on his social media platform Truth Social, where he stated that the United States was ready to act if Iranian authorities violently suppressed peaceful demonstrators.

The protests, now in their fifth consecutive day, have spread to more than a dozen cities including Tehran, Isfahan, Lorestan, Mazandaran, Khuzestan, Hamadan, and Fars. Local sources reported at least seven deaths in clashes between protesters and security forces. Demonstrators have been calling for the resignation of Supreme Leader Ayatollah Ali Khamenei and an end to the current political system.

The exchange of warnings between Washington and Tehran underscores rising tensions amid expanding unrest across Iran, with both sides signaling readiness for escalation if violence intensifies.
