Iranian Foreign Minister Abbas Araghchi has attributed the Syrian army's collapse to psychological warfare, warning that the rapid fall of the country's ally in Syria should serve as a cautionary tale for Tehran.

"The blow dealt to the Syrian army was more psychological than military," state-run media quoted him as saying in an event on Tuesday.

"The Syrian army was defeated before even engaging in battle and could not stand its ground. This must serve as a significant warning to us," he added.

He said Iran's adversaries are leveraging new technologies, media and cyberspace to weaken its allied groups in the region.

"We must not allow our enemies to use media platforms to sow despair, instability, hopelessness, frustration or depression in people's spirits," he said.

Last month, `Iran's Supreme Leader Ali Khamenei criminalized public discussions about Iran’s weakening position after the fall of Bashar al-Assad’s government in Syria.

Iran's Attorney General's Office later warned media outlets and online activists to avoid discussions on the topic, saying it could undermine domestic security.
