The director of the Atomic Energy Organization of Iran (AEOI) says Iran's defensive readiness is at such a level that "Israel" will never be able to attack the Islamic Republic's nuclear installations.

Ali-Akbar Salehi ruled out the possibility of any attack on Iran's nuclear facilities as he was asked about the "Israeli" threats against Iran's nuclear program.

Even though officials of "Israel" have repetitively declared their determination to halt Iran's nuclear program, even through resorting to military option- noting that the Zionist state is the only player in the Middle East region that possesses a nuclear arsenal- yet Salehi assures no installations will be attacked.

"We have taken all the necessary defensive precautions, including air defenses, and we hold regular maneuvers at the nuclear sites. So I assure the great Iranian nation that the installations will not be attacked," the Fars news agency quoted Salehi as saying on Tuesday.

However, Iran will still take any threat seriously, he stressed.

"We have taken all precautions and we are sure that no military attack will be able to stop Iran's nuclear program," Salehi stated.
