By Parisa Hafezi and Justyna Pawlak ANKARA/BRUSSELS (Reuters) – A deal between Iran and six major powers intended to pave the way to a solution to a long standoff over Tehran's nuclear ambitions will come into force on January 20, the Iranian Foreign Ministry and the European Union said on Sunday. Shortly after the interim accord takes effect, an Iranian official added, Tehran and world powers will start negotiating a final settlement of their differences about activity the West suspects is aimed at obtaining a nuclear weapons capability. Iran says its atomic energy program is aimed purely at electricity generation and other civilian purposes, although past Iranian attempts to hide sensitive nuclear activity from U.N. non-proliferation inspectors raised concerns. The November 24 agreement appeared to halt a slide towards another, wider Middle East war over Iran's nuclear aspirations, but diplomats warn it will not be easy to carry out because of long-standing mutual mistrust.
