Iran denies report linking Iraq cooperation to nuclear talks

DUBAI (Reuters) - Iran denied a report that it is ready to help counter Islamic State insurgents in return for progress in negotiations with world powers over its nuclear programme.

    France, one of the six nations in nuclear talks with Tehran, said on Wednesday it wanted Arab states, Iran and the five permanent members of the U.N. Security Council to coordinate a comprehensive response against Islamic State, whose militant forces control large parts of Syria and Iraq.
