Iran has long sought a self-sufficient military program and top officials frequently make announcements about the country's strides in military technology.
Tehran has recently said it has upgraded the accuracy of its missiles with a range of 2,000 kilometers (1,250 miles), which covers much of the Middle East, including Israel and U.S. bases in the Gulf.
However, it is virtually impossible to independently determine the actual capabilities or combat worthiness of Iran's arsenal.
Separately, the foreign ministry said a recent U.N. report that condemned Tehran of "deeply troubling" human rights violations was politically motivated and influenced by western adversaries including the United States.
The report, obtained by The Associated Press on Thursday, said many of the government's violations were "systemic in nature." It also called for an extensive, impartial, and independent investigation into the violence in the months that followed the re-election of President Mahmoud Ahmadinejad in 2009.
