"Approval of any new sanctions will be tantamount to terminating the ongoing nuclear talks," Iranian Foreign Ministry spokeswoman Marzieh Afkham said.

　　Afkham's comments came as a reaction to a sanctions bill pushed by the U.S. senators to slap new embargo on Iran which would require further reduction in Iran's oil exports.

　　"The attempt by U.S. Senate and Congress for imposing new sanctions will push the trend of talks between Iran and the P5+1 toward failure," said Afkham.

　　The Islamic republic is in talks with six world powers, including United States, Britain, France, Russia, China and Germany, regarding the implementation of an interim nuclear deal sealed between Iran and the powers in November last year in an attempt to end a decade-long disputes over Iran's controversial nuclear program.
