Iranian police have arrested major protest leaders amid two weeks of nationwide unrest. Police chief Ahmad-Reza Radan said on state TV, "Last night, significant arrests were made of the main elements in the riots, who, God willing, will be punished after going through legal procedures." The number of arrests was not specified. Iran's attorney general warned that protesters or helpers could be charged as "enemies of God," punishable by death. The protests started over a falling currency but expanded to calls for political reform and government downfall. The unrest is Iran's biggest in years, growing as the government faces an economic crisis and fallout from a recent conflict with Israel. Authorities cut internet access last Thursday, creating a near-total blackout. Human rights groups report this helped the government crack down brutally, using live ammo. At least 116 protesters have died and 2,600 arrested, said the US-based Human Rights Activists News Agency. "Examination of the causes of death shows that most victims were killed by live ammunition or pellet gunfire, predominantly from close range," the group added. US President Donald Trump warned of intervention if protesters are killed. On Truth Social, he said, "Iran is looking at FREEDOM, perhaps like never before. The USA stands ready to help!!!" Reports say Trump has military options but no decision yet. US senators like Lindsey Graham also backed the protests' end. Israel remains alert for US moves but stays quiet to avoid Iranian claims the unrest is foreign-backed. Iranian parliament speaker Mohammad-Bagher Ghalibaf responded sternly: "In the event of an attack on Iran, both the occupied territory and all American military centres, bases and ships in the region will be our legitimate targets." Despite the harsh crackdown, protests continue. Thousands protested in northern Tehran banging pots and chanting. In Mashhad, birthplace of Supreme Leader Ali Khamenei, activists blocked roads and lit fires. Reports indicate hundreds of protesters have died, but full counts are difficult due to communication blackouts. Some messages reach outside the country via Starlink internet. A protester in Sari said the city is under martial law with armed checkpoints threatening to shoot anyone outside. An activist told the Guardian her cousin fled after security forces opened fire with military weapons on unarmed protesters, shooting men, women, and children at close range. Videos show large crowds and gunfire sounds. The Hengaw rights group shared images of bodies of protesters killed at a warehouse in Tehran used as an overflow morgue. Iranian state media blamed protesters for the deaths. Iran's President Masoud Pezeshkian urged dialogue but stressed not allowing "a group of rioters to come and destroy the entire society." Iran is bracing for possible US or Israeli strikes while battling protests at home.
