Talks on Tehran’s nuclear programme go into a second day with Washington warning it will not rush into any deal.
A raft of sticking points remain to be resolved despite Wednesday’s “positive discussions.”
Iran has said that the right to carry out uranium enrichment is “non-negotiable” and that trust needs to be restored.
Iran’s Deputy Foreign Minister Abbas Araqchi said: “What we are trying now is to rebuild the confidence that we lost in the previous round of negotiations, because of the misunderstanding or, I don’t know, mismanagement of the previous round. We have not started any serious negotiations on any text yet.”
The talks, due to conclude on Friday, involve Iran, the US, the UK, China, Russia, France and Germany.
French Foreign Minister Laurent Fabius believes a deal is possible as long as negotiators remain “firm.”
Euronews correspondent in Geneva Fariba Mavaddat says: “The strong statements coming from both camps are designed for domestic audiences. Behind the facade there are signs that an agreement is still possible.”
