The nuclear deal between Iran and major powers could "normalise" Tehran's international relations and even help resolve certain crises in the Middle East, France's foreign minister said Tuesday.

"This is an historic deal in its aim and because it can help facilitate a normalisation of Iran's international relations," Laurent Fabius said, adding that he hoped it would "help a certain number of crises in which it (Iran) is directly or indirectly involved be resolved more easily."
