Iran says it will resume some of its nuclear fuel activities on Monday after failing to end a diplomatic row with the European Union.
It comes after the EU said Tehran would have to wait a week for new proposals despite an Iranian ultimatum for them to be issued today (Sunday).
But the EU, represented by Britain, France and Germany, said that would be an “unnecessary and damaging” step, adding that it is seeking clarification of Iran’s intentions.
According to the Islamic Republic, the EU was expected to offer a package of economic and political incentives in return for Iran’s indefinite suspension of its nuclear work.
Tehran maintains it only wants nuclear power to generate electricity and that the resumption of research activities would not include uranium enrichment.
However the EU and the United States suspect it is trying to develop nuclear weapons.
