TEHRAN, October 4 (RIA Novosti) - Iran will proceed with the development of its nuclear program, the Iranian president said Wednesday.

Some countries suspect Iran of pursuing a covert weapons program, but Tehran has consistently denied the allegation, saying it needs nuclear energy for electricity.

"Iran will not retreat even a step from its legal rights [in the nuclear sector], and will pursue its course with dignity," Mahmoud Ahmadinejad said.

Iran failed to meet the UN Security Council's August 31 deadline for suspending its nuclear activities, and the United States has pressed for sanctions against the country. Russia and China, however, hold vetoes in the council and oppose sanctions.
