A delegation from the International Atomic Energy Agency (IAEA) and Iranian officials continued their new round of talks on Iran's nuclear program on Wednesday, local Fars news agency reported.
The two sides started the new round of talks with a four-hour-long meeting on Tuesday and they would continue their talks on Thursday, Fars quoted "an informed source" as saying.
Results of the current talks between Iranian and IAEA experts in Tehran on the issues related to the Islamic Republic's P1 and P2 centrifuges will be announced late October, the source said.
He further described the talks between Tehran and the UN nuclear watchdog as "successful", but declined to reveal contents of the talks.
The IAEA delegation is headed by the agency's Deputy Director-General Olli Heinonen and the Iranian side is led by deputy head of Iran's Supreme National Security Council Javad Vaeedi, according to Fars.
Compared with P1, P2 centrifuges are more advanced and could produce more uranium, which can be used as nuclear fuel or key material for atomic weapons at the same time.
The new round of Iran-IAEA talks is being held based on an agreement reached between the two sides in August which called for removing all outstanding issues on Iran's nuclear program upon a specified time-table.
The UN Security Council has adopted two resolutions — one in December 2006 and the other in March this year — to force Iran to suspend uranium enrichment activities and to give up its nuclear program.
The United States and other Western nations have constantly accused Tehran of developing a nuclear weapon program under the guise of a civilian-use program, which was repeatedly denied by Iran.
Iran has insisted that its nuclear program is for peaceful purposes and voiced hope for talks to defuse the nuclear standoff.
