FRANTZMANJULY 18, 2026 16:07On July 17, Iran claimed it had attacked a United States “special operations command center in Tanf” in southern Syria.There were several problems with the claim. The US denied that troops had been harmed in the attack. A Syrian military source told reporters that there had been no attack.Tanf was once a small US garrison in southern Syria near where the Iraq-Syria-Jordan borders meet. The US withdrew from the Garrison earlier this year.Why would Iran claim to attack an area that is apparently abandoned?The reason for the attack was that on July 16 Syrian security forces had stopped a shipment of weapons to Hezbollah that was coming from Iraq.Cars and coaches line up at al-Tanf crossing on the border between Iraq and Syria, some 300 km southeast of Damascus March 20, 2003.

Iran wants weapons to continue to flow to Hezbollah via Syria.Before the fall of the Assad regime, this was the case.After the fall of the Assad regime, the new government in Syria has worked to stop Hezbollah smuggling. Not only is the new government stopping the smuggling, it is also calling out Hezbollah by name in announcements.By extension, it is putting a spotlight on Iraq because the weapons are coming from Iraq. The weapons likely are being smuggled by Iranian-backed militias in Iraq.The US is trying to get Iraq to disarm these militias. Iraq has said it will seek to do so. The US military is scheduled to leave Iraq in September.Iran is worried that its ability to control Iraq via militias and also export arms to Hezbollah is being challenged.Syria has already rolled by the Iranian influence. However, Iran still has Iraq, and it can move weapons via civilian vehicles and then try to sneak them through Syria.Iran lashes out at neighboring countriesIran’s decision to claim it attacked Tanf is a message for Syria. Iran has already attacked other states in the region. It usually targets US facilities in some of these states, but it is also increasingly lashing out at countries such as Kuwait and the Kurdistan Region of Iraq. This is happening amid the US week-long bombing campaign on Iran that began on July 7 after Iran attacked tankers in the Gulf.With so many frontlines, Iran is seeking to keep Syria out of the conflict. Tanf was an easy target because Iran likely knows it is abandoned. It’s possible that there are some residual forces there, from Syria possibly. The US trained a Syrian rebel group in Tanf before the fall of the Assad regime. The group then integrated with the Syrian security forces. The area of Tanf is a strategic area. As such, it’s likely Syria wants to maintain forces here.Iran has carried out attacks in Syria in the past. It once used ballistic missiles to attack what it claimed were ISIS targets.Its most recent use of the missile in Syria was in January 2024 before the fall of the Assad regime. Iran’s Kataib Hezbollah militia in Iraq also attacked a Jordanian site called Tower 22 near the Syrian border in January 2025, killing three Americans.As such, Iran has long experience threatening Syria, Jordan and Iraq. It remains to be seen if Iran will try to expand the war to Iraq. It has already done so to northern Iraq, attacking Kurdish sites.Follow us on Google
