TEHRAN, Feb. 25 -- Iranian President Hassan Rouhani said Tuesday that the Islamic republic is determined to continue its nuclear talks with the P5+1 group until "a final victory" is achieved for the Iranian nation, Press TV reported.

Rouhani said his administration of "hope and prudence" would not "take a single step back from protecting the nation's rights" in the nuclear talks with the six world powers in the group.

"We will continue these (nuclear) negotiations until a final victory for the Iranian nation is achieved," he was quoted as saying.

The Islamic republic should break the chain of "unjust" and " cruel" sanctions imposed on the country's economic sector, and Iran has taken the first step toward the removal of these "illegal " sanctions, he added.

Iran and the P5+1 group, including United States, Russia, China, France, Britain and Germany, clinched an interim nuclear deal in Geneva on Nov. 24, 2013, under which Iran suspended its 20-percent uranium enrichment and started the process of diluting and oxidizing its 196 kg stockpile of 20-percent enriched uranium in exchange for partial relief of the sanctions imposed on its energy and financial sectors.

On Sunday, Iranian Foreign Minister Mohammad-Javad Zarif said Iran was determined to continue nuclear negotiations with the world powers and also to counter any "excuse" for mounting sanction pressures.

After three days of intensive negotiations, EU Foreign Policy Chief Catherine Ashton and Zarif announced Thursday the timetable for the next round of talks.
