PARIS, November 9. /TASS/. Nine people were killed in a US air strike on a facility in Syria, reportedly used by the Iran's Islamic Revolutionary Guard Corps (IRGC) and affiliated groups, Agence France-Presse reported on Thursday citing the Syrian Observatory for Human Rights.

"Nine people working for Tehran-backed groups were killed in US strikes on sites used by pro-Iran groups," the agency quoted a spokesman for the organization as saying.

US Secretary of Defense Lloyd Austin said in a statement earlier in the day that the strike was conducted by two F-15 fighter jets of the United States and targeted a weapons storage facility. It came as "a response to a series of attacks against US personnel in Iraq and Syria."

According to Deputy Assistant Secretary of Defense for the Middle East Dana Stroul, US facilities in Iraq and Syria have been attacked 41 times since October 17, by armed groups supported by Iran.
