Iran on Sunday vowed to push ahead its nuclear work despite more severe sanctions imposed by the UN Security Council against the Islamic Republic's nuclear program.

Iranian President Mahmoud Ahmadinejad was quoted by state television as saying that new sanctions "will not halt Iran's peaceful and legal nuclear program even for a second."

He warned that the Iranian people would not forget "the hostility of those countries" which opposed Tehran's nuclear program.

On Saturday, the UN Security Council unanimously adopted

Resolution 1747, which was moderately harsher than those included in previous resolutions on the Iranian nuclear issue.

Resolution 1747, cosponsored by Britain, France and Germany and incorporating some of the amendments proposed by Indonesia, Qatar and South Africa, urges Iran to suspend uranium enrichment work " without further delay" or facing a ban of Iranian arms exports, a freeze of assets of an additional 28 individuals and entities involved in Iran's nuclear and missile programs.

It also asks the International Atomic Energy Agency (IAEA) to report back in 60 days on whether Iran has suspended enrichment work.

Earlier in the day, Iranian government spokesman Gholam-Hossein Elham said his country decided to limit its cooperation with the IAEA after the new sanctions were adopted.
