This is the first time a foreign power has used an Iranian base since World War II
Iran said on Monday that Russia has stopped using an Iranian air base for strikes in Syria, a week after Moscow announced that its fighter-bombers had flown from a base in Iran to hit targets in Syria.
"Russia has no base in Iran and is not stationed here. They did this (operation) and it is finished for now," Iranian foreign ministry spokesman Bahram Qasemi was quoted as saying by Tasnim news agency.
Long-range Russian Tupolev-22M3 bombers and Sukhoi-34 fighter-bombers used Nojeh air base, near the city of Hamedan, in north-west Iran to launch the air strikes last week, in a move which underscored Moscow's increasingly close ties with Tehran.
But the deployment, the first time a foreign power has used an Iranian base since World War Two, triggered criticism from some Iranian parliamentarians who said it breached the Islamic Republic's constitution.
Iranian defence minister Hossein Dehghan dismissed that criticism on Sunday, but also chided Moscow for publicising the move, describing it as showing off and a "betrayal of trust".
"We have not given any military base to the Russians and they are not here to stay," Dehghan was quoted as saying by the Fars news agency.
He said there has been "no written agreement" between the two countries and the "operational cooperation" was temporary and limited to refuelling.
