Iran has announced it will resume its controversial nuclear programme imminently in the face of a European Union appeal to wait for talks. Officials said they would inform UN nuclear inspectors of the move on Monday and then begin converting raw uranium at a plant in Isfahan. The UK, which is leading EU attempts to negotiate a compromise, said the move would make further talks difficult. Iran has rejected the charge that it is pursuing nuclear weapons. It suspended all uranium conversion and enrichment activities in November 2004 as a result of international pressure. Enriched uranium can be used to fuel nuclear power stations but can also provide material for nuclear weapons.
