Iranian security forces have arrested roughly 500 people across the country on espionage charges, accusing them of collecting and transmitting sensitive information about military sites, airstrike locations, and emergency response operations to foreign intelligence agencies and opposition media outlets.
The mass arrests represent the most aggressive domestic security operation since the war began, carried out under an internet blackout that has severed most independent channels for verifying the government's claims.
Authorities say the detainees were not ordinary bystanders or journalists but active operatives engaged in systematic intelligence gathering that posed a direct threat to national security.
Rights groups and families of those detained say the espionage label is being applied so broadly that it sweeps up anyone who documents the war or shares information with the outside world.
The crackdown comes at a moment when Iran is fighting on multiple fronts against Israel and the United States, managing the political transition following the death of Supreme Leader Ali Khamenei, and contending with the aftershocks of the anti-government protests that swept the country in late December.
Authorities have framed the arrests as part of a total war that extends beyond the battlefield to include what officials describe as an information front of equal strategic importance. No transparent process Those detained fall into several categories, according to official statements. Some are accused of photographing airstrike sites and military installations and sending the images to foreign parties.
Others are alleged to have collaborated with opposition media, particularly the London-based channel Iran International , which Iranian authorities consider an instrument of hostile intelligence services.
A third group is accused of direct contact with foreign intelligence agencies in the Middle East and Europe.
Authorities said some of those arrested had transmitted information about the locations of emergency rescue teams, which the state described as an additional crime because such data could be used to disrupt humanitarian operations during the conflict.
No transparent legal proceedings have been announced for any of the detainees. Security officials have said that any cooperation with opposition media or foreign intelligence constitutes a national crime punishable under Iranian law with severe sentences, including lengthy imprisonment.
The father of Hadi Reza Khalili, a man detained in Tehran, said his son had lived an ordinary life with no public political activity and had never participated in any protest.
"Suddenly, he was arrested and charged with espionage," the father, 55, said. "The authorities considered him an agent of the enemy.
"We live in permanent fear. We don't know when it will be the turn of the next family member. Everything is now monitored, from phone conversations to internet use. We avoid talking about anything sensitive."
The espionage charges are being used as a tool of pressure and control rather than a means of enforcing the law, he added.
"This leaves a long-term impact on the mental health of those affected and on citizens' sense of belonging."
In Qom, the mother of Samira Ali Mousavi, who was detained a week ago, said the family has been unable to obtain any details about her daughter's condition or the specific charges against her. She asked to be identified only by her first name, Zahra, 50.
"The authorities' description of the charges as 'espionage' is extremely vague and does not allow any family to understand the nature of the alleged crime," Zahra said. "This reflects the use of these charges as a tool of deterrence more than a means of justice."
She said the arrests have created a climate of fear across the community.
"Residents live in a state of suspicion about every action or conversation that could be interpreted as a violation. From our perspective, espionage charges are being used systematically against anyone who could represent a symbolic threat to the system, even if their activities were entirely legitimate." A war on information The arrests are part of a broader strategy that combines the internet shutdown, the blocking of communication apps, and the detention of anyone suspected of sharing information outside state-controlled channels.
Mostafa Khalilzadeh, an Iranian journalist who works with an international Arabic-language news platform, said the crackdown reflects a comprehensive strategy to control the domestic narrative rather than a routine judicial operation.
"These arrests are not simply a reaction to potential leaks," he said. "They are part of the state's logic of securing what it considers national security by creating a climate of terror and social discipline that prevents any attempt at leaking or criticism."
The definition of espionage has become so broad that it encompasses any media activity or information-sharing that authorities can interpret as a threat, even if the activity involves nothing more than documenting events or reporting news, Khalilzadeh said.
"This not only affects the lives of detainees and their families," he said. "It also limits the ability of media to cover conditions objectively and places restrictions on investigative journalism that could expose mismanagement or internal violations."
Imad Abshenass, a former media adviser to President Hassan Rouhani, said the arrests represent a crisis of trust between the state and society.
"The phenomenon is not new, but it has become more severe in recent years as a result of military escalation and regional conflicts," he said. "Internally, it generates fear and confusion among citizens and restricts basic freedoms. Externally, it exposes Iran to criticism and weakens its political credibility, especially before international partners."
Journalism and media in Iran face a double challenge, Abshenass said. Local coverage is restricted, and any content interpreted as a leak can lead to arrest.
"This reflects the state's use of psychological and social deterrence more than legal or security measures," he said, "creating a permanently tense environment that makes internal dialogue nearly impossible." Long-term damage A researcher at the Iranian human rights organisation Human Rights Activists News Agency (HRANA), who asked for his identity to remain anonymous for security reasons, said the mass arrests and espionage charges reflect an escalating pattern of using security authority to suppress any independent or critical activity.
"From a human rights perspective, what is happening is a clear violation of the principle of criminal justice," he said. "The accused are deprived of transparent trials, and the right to defence, and broad charges are used as a tool to control society."
The impact on Iran is wide, he said. The arrests create an environment of fear and self-censorship, undermine citizens' trust in state institutions, and weaken public participation in civic or media activities. Internationally, these practices expose Iran to rights-based criticism and increase the likelihood of further political and economic isolation.
Alireza Ardan, an Iranian researcher, said the mass arrests signal a shift in the relationship between the state and its citizens. The government now views any media, academic, or even community activity with suspicion, he said.
"This approach creates an environment of permanent self-surveillance where everyone feels monitored, and any statement can be interpreted as a threat to national security," Ardan said. "The arrests reflect the system's policy of tying internal security to external security, using espionage charges as a tool to subjugate society."
Over the long term, he said, the continuation of these policies will deepen the disconnect between the state and the public and weaken Iran's ability to adapt to regional and international changes. This story is produced in collaboration with Egab .
