Iran to freeze nuclear talks if new sanctions imposed

Iran will not continue negotiations on its nuclear program if the UN
Security Council imposes new sanctions against Tehran, RIA Novosti
reports, citing Iranian President Mahmoud Ahmadinejad.
"I've already said that it is a big mistake by the US administration
and its allies if they think that at the same time they can threaten
us with UN sanctions and sit with us at the negotiating table. This
won't work," Ahmadinejad said during a CICA summit in Turkey.
He also said that May's Brazil-Turkey-Iran deal on uranium exchange
was the West's last chance to reach an agreement on Iran's nuclear
program.
