Iran's Supreme Leader Ayatollah Ali Khamenei claimed Tehran possesses evidence that the United States and Israel orchestrated the collapse of Syria's Assad regime, according to Iranian state news agency IRNA.

The comments come just days after Syrian President Bashar al-Assad fled to Moscow following the rapid capture of Damascus by opposition forces led by Hayat Tahrir al-Sham (HTS) and its leader Abu Mohammad al-Jawlani, marking a dramatic end to the Assad family's decades-long rule over Syria.
"There should be no doubt that what happened in Syria is the result of a joint American and Zionist plan," Khamenei said, according to IRNA, in his first public comments since the fall of his longtime regional ally.
In his remarks reported by IRNA, Khamenei alleged that while a neighboring country – presumably Turkey – has played an evident role in Syria's situation, the primary responsibility lies with Western powers. "Yes, the neighboring country of Syria has played a clear role in this matter and continues to do so – this is evident to all – but the primary conspirator, the main planner, and the central command room are in the United States and the Zionist regime," he said.
The Supreme Leader further claimed to have definitive proof of these allegations, stating: "We have evidence. This evidence leaves no room for doubt." The statement marks Iran's first official response to the fall of Assad's government, which Tehran had supported militarily and financially throughout Syria's civil war.
