Tehran: Iranian leaders vowed yesterday to press on with Tehran's disputed nuclear work regardless of any new UN sanctions, one day after world powers agreed the outline of a new resolution.

"The Iranian nation has chosen its path and will continue with it," President Mahmoud Ahmadinejad was quoted as saying by the students news agency Isna.

"Such illegal behaviour [by Western powers] ... will not divert the Iranian nation from its path."

World powers agreed on Tuesday on the outline of a third sanctions resolution against Iran, but diplomats said the draft did not contain the punitive economic measures that Washington had been pushing for.

"We advise them not to repeat their previous mistakes .... They cannot make up for the past with a new mistake," Ahmadinejad said.

German Foreign Minister Frank-Walter Steinmeier said in Berlin on Tuesday after a nearly two-hour meeting with his counterparts from Britain, China, France, Russia and the United States, that the new draft of a sanctions resolution would be presented to the UN Security Council .

Russian Foreign Minister Sergei Lavrov said the new draft resolution was not tough or punitive and "welcomes the progress made between Iran and the International Atomic Energy Agency". "Iran has gone beyond its obligations," Saeed Jalili, Iran's top nuclear negotiator, told a committee of the European Parliament during a visit to Brussels.
