TEHRAN, Oct. 21 (Xinhua) -- A senior Iranian security official on Monday rejected as "baseless" the claims that the United States has recently launched several cyber attacks against the Islamic republic, Tasnim news agency reported.
"The Americans have twice said that they have launched cyber attacks against Iran in response to Iran's (earlier) attack on the U.S. drone," Head of Iran's Civil Defense Organization Gholam Reza Jalali said on Monday.
"However, we have seen no sign of such cyber attacks," Jalali was quoted as saying.
On Wednesday, western media quoted U.S. officials as saying that Washington recently carried out a secret cyber operation against Iran in response to Iran's anti-U.S. moves.
In June, the Islamic Revolution Guards Corps (IRGC) shot down a U.S. spy drone over the Gulf for "violating" Iran's territorial waters.
