Tehran, Sep 9 (IANS): Iranian senior nuclear negotiator Abbas Araqchi Tuesday said Tehran will not tolerate further sanctions imposed on it by the US.

"In our bilateral talks with the US officials, we have announced it clearly that we will not stand these measures any longer," Xinhua quoted Araqchi as saying.

The US has imposed new sanctions on a number of Iranian individuals and entities while pledging to continue working toward a comprehensive solution to Tehran's controversial nuclear programme.

The US Treasury Department targeted the networks for their alleged support to Iran's missile and nuclear programmes as well as terrorism and for helping Tehran evade the existing sanctions.

"These kinds of sanctions go contrary to the spirit of goodwill that should govern the nuclear talks," Araqchi said.

Araqchi referred to the recent talks between Iran and the US over the issues pertaining to the former's sensitive nuclear programme, saying that "there is a good interaction between the sides, but it does not mean that we have solved all our existing problems".

He expressed concern about any failure to clinch a comprehensive nuclear deal, adding that the outcome will further complicate the region's problems and it will be "very dangerous".

Iran and the P5 1 group, or the five permanent UN Security Council members (China, France, Russia, Britain, and the US) plus Germany, agreed July 19 to extend the talks until Nov 24 as disagreements remained over Tehran's uranium enrichment capacity and other issues.
