Iran has said it would resist Western pressure to make what it considered to be excessive concessions in nuclear talks in Vienna.
Negotiators from Tehran and six world powers are pushing to end a 12-year dispute over Iran’s nuclear programme.
The talks aim to reach a settlement that would curb Iranian atomic activities in return for the phasing out of sanctions, but officials admitted that that the November 24 deadline is unlikely to be met.
France, China, Russia, Germany, the United States and Britain want Iran to scale back its capacity to refine uranium, to prevent the production of a nuclear bomb, a key concern of neighbouring power Israel.
Tehran says that it is enriching uranium to make fuel for nuclear power plants.
Iran’s negotiator said any solution must respect Iran’s rights as well as allay the concerns of the international community.
