Iran’s Islamic Revolutionary Guard Corps said on Monday that unidentified groups operating from northern Iraq and allegedly acting on behalf of the United States and Israel had tried to transport a large cache of American weapons and ammunition into Iranian territory.

The accusations come amid heightened regional tensions following months of conflict involving Iran and Israel, despite a ceasefire announced in April.

Representatives of the Kurdish opposition groups, which maintain bases in Iraq’s autonomous Kurdistan region, dismissed the allegations as unfounded and politically motivated.

Party of Free Life of Kurdistan official Ahwan Chiako said claims regarding the seizure of weapons had “absolutely nothing to do with us.”

“We did not send weapons. No arms or equipment belonging to us have been seized by the Islamic regime,” Chiako told AFP.

Komala spokesperson Amjad Hossein Panahi said the accusations were “completely false” and served as justification for continued Iranian missile and drone strikes targeting areas in Iraq’s Kurdistan region.

An official from the Democratic Party of Iranian Kurdistan, speaking anonymously because he was not authorized to address the media, also denied any involvement in weapons transfers into Iran.

Tehran has long accused Kurdish armed factions based in Iraq of collaborating with Western governments or Israel and classifies several of the groups as terrorist organizations.

Iran has repeatedly conducted cross-border missile and drone strikes against Kurdish opposition positions in Iraq since the outbreak of the broader Middle East conflict, although many camps and facilities had reportedly been evacuated before the attacks intensified.

Earlier in the conflict, speculation emerged in regional media suggesting that Kurdish opposition groups might coordinate with the United States in the event of wider instability inside Iran. Iranian authorities subsequently warned they would target any militant activity launched from Iraqi Kurdistan.

Deputy Prime Minister of Iraq’s Kurdistan region Qubad Talabani said in March that the United States was not supplying weapons to Iranian Kurdish opposition groups.

US President Donald Trump had earlier suggested support for anti-government unrest inside Iran before later stating that attempts to arm Iranian protesters had failed because Kurdish intermediaries allegedly diverted the weapons.

The suspect, identified as Shamim Mafi, is accused of brokering deals involving drones, bombs, bomb fuses and large quantities of ammunition between Iranian entities and the Sudanese Armed Forces, according to statements by U.S. Attorney Bill Essayli.

Mafi, an Iranian national who became a lawful permanent resident of the United States in 2016, was taken into custody on Saturday night and is scheduled to appear in federal court in Los Angeles on Monday. Authorities said it was not immediately clear whether she had secured legal representation.

A criminal complaint filed on March 12 alleges that Mafi and an unnamed associate operated a company based in Oman, Atlas International Business, which prosecutors say was used to channel arms transactions. The firm reportedly received more than $7 million in payments in 2025 linked to these activities.

Court documents also allege that Mafi helped arrange the sale of 55,000 bomb fuses to Sudan’s Ministry of Defense and submitted a letter of intent to Iran’s Islamic Revolutionary Guard Corps to procure the materials.If convicted, Mafi could face a maximum sentence of 20 years in prison.

The case comes amid Sudan’s protracted civil war, now in its fourth year, which has triggered a severe humanitarian crisis marked by widespread displacement and acute shortages of food and basic supplies.
