Keivan Khosravi, spokesman for Iran's Supreme National Security Council, issued the warning on Saturday after American officials claimed that Iran has been involved in attacks on illegal US bases inside the Syrian territory.
According to Iran's Arabic-language television news network al-Alam, more than 20 rockets were reportedly fired on Saturday against two illegal bases belonging to American occupation forces in eastern Syria.
The television network specified the targets as American outposts based near the al-Omar oilfield and the Koniko gas field in Syria's Deir ez-Zur Province.
The attacks came in response to a strike carried out by US forces against a facility in northeast Syria, following a drone attack on Thursday that killed a US contractor and injured six other Americans, Press TV reported.
Khosravi said the US is trying to level accusations against Iran by pursuing a blame game policy and evading the consequences of its illegal occupation of a part of Syria's territory, adding that such claims are not true.
"Washington cannot attribute the natural and legal confrontation of the occupied countries with the US military forces to other countries by creating artificial crises and lying," the Iranian security official emphasized.
He said Iran has incurred huge costs in the fight against terrorism and in establishing lasting security in Syria, adding that Tehran "opposes and counters any action that jeopardizes stability of this country."
The spokesman said the US has played a role in creating and supporting Daesh terrorist group as a proxy means to pursue its own political objectives in Syria and Iraq.
