Russia’s use of an air base in western Iran to launch attacks inside Syria has come to an end for now, according to Iranian officials.

Russia became the first foreign military since World War II to use Iranian soil to launch a military attack last week when long-range Tupolev-22M and Sukhoi Su-34 bombers took off from Hamedan air base. The news, which was first revealed by Russian officials, led to a great deal of commentary both internationally and domestically. A number of Iranian parliamentarians had raised objections, arguing the military influences of superpowers in Iran have had a damaging impact on the country and that the establishment of a foreign military base is against Iran’s constitution.

In an Aug. 22 news conference, Foreign Ministry spokesman Bahram Ghasemi tried to allay those fears. “Regarding the situation with Russia, what was done was a temporary act and coordinated,” said Ghasemi. “I must emphasize that Russia neither has a base in Iran nor is it stationed here. It was temporary, and it has ended for the time being.” 

In response to a reporter’s question about why the news was first announced by the Russians, Ghasemi said both Iran and Russia had agreed they would announce the operation at the same time but added that possibly due to the time difference Russia announced it first. However, he said that Ali Shamkhani, the secretary of Iran’s National Security Council, immediately confirmed the news shortly after. He added that the announcement was “nearly simultaneous.”
