Land subsidence driven by decades of groundwater over-extraction is emerging as a direct threat to some of Iran’s most treasured heritage sites, including Persepolis, Naqsh-e Jahan Square and the Tomb of Cyrus, Iranian scientists and officials say.
Geologists cited by Tasnim news agency said subsidence has accelerated across provinces such as Isfahan, Fars and Tehran, with field observations of cracks, surface fissures and foundation instability near historic structures.
“Nearly half of Iran’s valuable historic fabric lies in subsidence-prone zones,” geologist Ali Shahbaz was quoted as saying, adding that “63 nationally registered monuments and 27 world-class sites” are in affected areas.
In Isfahan, the long-dry Zayandehrud river has been linked to ground settlement of roughly 16-25 cm a year in the city’s north, raising stability concerns for Naqsh-e Jahan Square, the Shah and Sheikh Lotfollah mosques, and the Safavid-era Si-o-se-Pol and Khajou bridges, Tasnim reported.
In Fars province, subsidence in the Marvdasht plain -- estimated around 14 cm a year -- has prompted warnings about drainage systems and stone platforms at Persepolis and potential long-term risks to the Tomb of Cyrus at Pasargadae and the rock-cut tombs of Naqsh-e Rostam.
The concerns come amid broader alarms over nationwide land-subsidence.
Tasnim, citing official tallies, said 380 cities and about 9,000 villages have reported some level of subsidence, with roughly 42 million people living on sinking ground.
Iran’s Geological Survey says two decades of drought and sustained over-pumping, compounded by fragmented water governance, have pushed 106 plains into non-recoverable subsidence.
Cultural-heritage specialists stress there is no immediate risk of collapse at marquee sites, but warn that cumulative deformation, coupled with drying soils and sporadic heavy rains, could inflict irreversible damage over years to decades.
“No site is on the brink today,” Shahbaz said. “But without curbing withdrawals and restoring groundwater, we are setting the stage for losses that cannot be repaired.”
The Mossad named Sardar Ammar, a senior Quds Force officer operating under commander Esmail Ghaani, as the leader of a network responsible for planned operations in Australia, Greece, and Germany during 2024-2025, a statement released via the prime minister’s office on behalf of the Mossad said on Sunday.
The Mossad described the network’s methods as “terror without Iranian fingerprints,” using foreign recruits, criminal intermediaries, and covert communications to conceal Tehran’s role.
“Thanks to intensive activity with partners in Israel and abroad, dozens of attack tracks were thwarted, saving many lives,” the statement said.
In August, Australia expelled Iranian Ambassador Ahmad Sadeghi and announced plans to designate the IRGC as a terrorist organization, after intelligence linked Tehran to antisemitic arson attacks in Melbourne and Sydney. Sadeghi denied the allegations upon his departure.
In Germany, authorities summoned Iran’s ambassador, Majid Nili Ahmadabadi, in July after the arrest of a Danish suspect accused of spying on Jewish and Israeli-linked sites in Berlin for Iranian intelligence. German officials said the surveillance could have been preparatory to terrorist attacks.
Iran’s covert campaign and regional reach
The Mossad accused Iran of pursuing a long-term strategy “to harm innocents around the globe while maintaining deniability,” but said the recent revelations “strip Iran of its space for denial and impose heavy diplomatic costs.”
The statement cited earlier cases in Greece as part of the same pattern. In 2024, Greek police arrested suspects, including Iranian and Afghan nationals, over arson attacks on an Israeli-owned hotel and a synagogue in Athens.
A year earlier, two Pakistani men were charged with plotting attacks on Israeli and Jewish sites in the city under Iranian direction.
The dismantling of Ammar’s network and the resulting diplomatic pressure, the Mossad said, marked a significant blow to Iran’s covert operations abroad, demonstrating what it called the Islamic Republic’s “repeated operational failures and growing international isolation.”
Ahmad Moghadasi, chairman of Iran’s Cattle Farmers Association, told state media that provinces including Tehran, Alborz, Qazvin, Qom, and Markazi have reported widespread infections, including among vaccinated herds.
“Even herds that were immunized have been struggling for over three weeks without recovery,” he said, blaming the introduction of a new SAT1 African strain of the virus.
He warned that the epidemic, coupled with the near-total halt of government feed distribution, has left dairy farms facing critical shortages.
“No feed is available in the agriculture ministry’s online system,” Moghadasi said. “Farmers are forced to buy on the open market, where corn costs 360,000 rials (about 33 USD cents) per kilo and soybean meal 400,000 rials (about 37 cents) -- double official rates.”
The government had set a purchase price of 230,000 rials (about 21 cents) per kilo for raw milk, based on subsidized feed costs, but the official system has failed to deliver supplies, Moghadasi added. “The government has not met its commitment, so input prices and milk prices are both rising,” he said.
Foot-and-mouth disease (FMD), a highly contagious viral infection affecting cloven-hoofed animals, has been reported in 270 locations nationwide, according to Iran’s Veterinary Organization.
Its head, Alireza Rafieipour, said more than 36 million animals have been vaccinated this year, adding that the situation remains under control with intensified quarantine and disinfection measures.
Industry groups, however, warn that recurring outbreaks and rising production costs are exacerbating Iran’s dairy crisis.
Domestic milk output and consumption have both declined amid inflation and poverty, with the Health Ministry reporting this month that per capita dairy intake has dropped to less than half the recommended level.
Officials blame soaring prices, reduced subsidies, and the lingering impact of US and UN sanctions on feed and veterinary imports.
The Agriculture Ministry has promised to stabilize supplies and maintain sufficient vaccine stocks, but farmers say they face mounting financial strain. “We are witnessing conditions similar to 2012 and 2018, when sanctions caused widespread drug and feed shortages,” according to Moghadasi.
According to the UN Food and Agriculture Organization, Iran’s per capita dairy consumption fell from 101 kilograms in 2010 to 70 kilograms in 2023, less than half the global average, reflecting a deepening food security crisis as inflation erodes purchasing power.
The State Attorney’s Office filed the indictment on Sunday at the Nazareth District Court against Rahman Gokayer, Younes Ozel, and Oktay Asci, accusing them of illegal entry, weapons trafficking, and ties to foreign arms dealers. Asci also faces a charge of aiding terrorist activities.
Gokayer and Asci traveled from Turkey to Saudi Arabia and then to Jordan in September 2025, where they agreed to infiltrate Israel and smuggle three handguns supplied by Iranian intermediaries, according to the indictment.
The plan was later abandoned after internal disagreements, but the two crossed illegally near Kibbutz Shaar HaGolan.
Asci had previously lived in Israel without a permit for more than two years before being deported in July 2025. During that period, prosecutors say, he obtained a firearm in Bat Yam, buried it near his apartment, and later handed it to an unidentified individual.
After his deportation, Asci maintained contact with Gokayer and Iranian brokers through Turkish intermediaries, planning to route guns from Iran to Jordan and into Israel via Palestinian laborers. Gokayer’s role was to collect the weapons, transfer them to others, and manage the proceeds, for a promised payment of one million dollars.
“The plan was to transport the guns to Jordan and smuggle them into Israel using workers crossing the border. Gokair was supposed to receive the guns and transfer them to other parties and collect the money from the transactions. For his role in the smuggling network, Gokair was promised a payment of $1 million,” reads the indictment.
Ozel, already in Israel, was told to complete a weapons deal in Tel Aviv but twice left empty-handed. Prosecutors say he kept 5,000 shekels from the funds meant for the transaction. All three men remain in custody.
Iranian smuggling networks foiled
Earlier this month, Israel’s Shin Bet security agency said it had thwarted a major Iranian attempt to move a cache of advanced weapons into the West Bank for planned attacks. The haul included explosive devices, drones, anti-tank weapons, grenades, rifles, and ammunition.
Shin Bet traced the operation to Iran’s Islamic Revolutionary Guard Corps, involving Unit 400 under Javad Ghafari and Unit 18840 in Syria, which reports to Asghar Bakri, head of the covert Unit 840. Two IRGC operatives killed in Israeli strikes in Lebanon in July -- Salah al-Husseini and Muhammad Shuayb -- were also involved.
Iran is pursuing a broader strategy to arm groups in the West Bank to attack Israeli civilians and forces, the agency said.
In March 2024, Shin Bet and the Israel Defense Forces intercepted another Iranian arms shipment that included grenade launchers, explosives, mines, and assault rifles.
