Iran has been testing new military defense systems, the head of the country's Revolutionary Guard said on Saturday.
"Our country is always the arena for testing a variety of defense and strategic systems ... and yesterday was one of the successful days for this nation," Revolutionary Guard commander Major General Hossein Salami said, according to the semi-official Tasnim news agency.
Hossein did not give details on the test and it was unclear whether new missiles were involved.
State media was yet to report on the development.
Iranian President Hassan Rohani on Thursday presented an upgraded Bavar-373 missile defense system, which was produced in the country. The Bavar equipment is designed to resemble Russia's S-300 defense system, although Rowhani claims that it is in fact even more precise and closer to the Russian S-400 model.
Iran has vowed to continue developing its missile arsenal despite international outcry, insisting that it will only use such missiles for self-defense.

The country's mid-range missiles are of particular concern to Israel, Iran's arch-enemy, which is within their range of 2,000 kilometres.
Tehran justifies its missile programme by pointing to perceived threats from the United States, Israel and Saudi Arabia.
