Iran's Islamic Revolutionary Guard Corps (IRGC) claimed on Friday they had attacked a US special operations command center at al-Tanf in Syria in retaliation for the killing of Iranian soldiers in Iranshahr, Iranian state media reported.
Reuters could not independently verify the claim, and there was no immediate comment from the Syrian government or the US military.
The US military said in February it completed a withdrawal from the al-Tanf base positioned at the tri-border confluence of Syria, Jordan and Iraq.
Syria has sought to avoid being drawn into the regional conflict that has engulfed neighboring countries, including Lebanon, where Hezbollah has fought Israeli forces, and Iraq, where Iran-backed armed groups have launched drone and rocket attacks.
Syrian President Ahmed al-Sharaa said in March that his country would stay out of any conflict unless it came under attack.
"Unless Syria is targeted by any party, Syria will remain outside any conflict," Sharaa said at an event hosted by the Chatham House think tank in London.
The IRGC also said Iran retained full control of the Strait of Hormuz and that no oil or gas would be exported through the waterway for as long as US attacks continued, according to the state media report.
Iran targets US base in Jordan, Qatar
Later on Friday, the IRGC-linked Tasnim news agency reported that the Iranian regime targeted the Muwaffaq Salti Air Base in Al-Azraq, Jordan.
The statement by the IRGC claimed that the attack involved "several ballistic missiles and numerous drones" and "resulted in the destruction of several American tankers and fighter jets and serious damage to many more of them."
No official statement was made by the US Central Command (CENTCOM) about an attack against its bases in the Middle East.
Additional attacks were reportedly made against the US Al-Udeid base in Qatar, while the IRGC warned that "any attacks against Iran would trigger more crushing retaliation against any country hosting American forces."
