Teheran, August 18 (KCNA) -- Iran will respond "decisively" if the United States or Israel attempt to attack the Islamic Republic, President Mahmoud Ahmadinejad told Russia Today.

"They wish to do it, they want to do it, but they know about our power. They know we are going to give them a decisive response. We have a saying in our language if someone throws a smaller stone, you should respond with a bigger stone. We will defend ourselves within our capabilities," Ahmadinejad said in an exclusive interview with the Russian network published Sunday.
