"Yes, they (the talks) were fruitful but they need to continue. This can take place either before or after the elections in Iran. Because these talks are happening at a national level and involve everyone in Iran. We support the Iranian public. So a decision has been made to continue negotiations and hold talks again in the near future."
"They rejected the Tehran declaration, they didn't accept it. And we hope that when the opportunity arises, they (P5+1) will take the Tehran declaration into consideration. At the first (P5+1) meeting in Almaty, they told us to think about the preparations for enriching uranium to 20 percent for Iran. I hope they think about that."
"The Republic of Iran since the very beginning has always opposed violence, has always opposed the use of arms. There's only one solution to the conflict in Syria and that's democracy and negotiation."
Iranian nuclear negotiator, Saeed Jalili, on Thursday described his talks with European Union foreign policy chief, Catherine Ashton, in Istanbul the previous day, as "fruitful".
At a news conference in the Turkish city, he said there was an opportunity for the talks to continue either before or after the upcoming Iranian elections.
"We support the Iranian public. So a decision has been made to continue negotiations and hold talks again in the near future," Jalili said.
His comments came a day after Iranian negotiators and United Nations nuclear agency officials in Vienna failed to reach a deal that would allow the agency to relaunch its probe of Tehran's nuclear programme.
The Vienna meeting was the 10th inconclusive meeting between the International Atomic Energy Agency (IAEA) and Iran on the issue over the past year and a half.
The last round of talks between Tehran and six world powers in Almaty, in Kazakhstan, last month ended in a stalemate.
The six nations (The US, UK, Germany, China, France and Russia) want Iran to stop enriching uranium to a level just a technical step short of the grade used to arm nuclear warheads.
The IAEA's investigation has stalled for more than five years, with Tehran saying it has answered all questions it is obliged to.
Commenting on the ongoing situation in Syria, Jalili said that his government "has always opposed violence, has always opposed the use of arms".
"There's only one solution to the conflict in Syria and that's democracy and negotiation," he said.
