Iranian Foreign Minister Mohammad Javad Zarif said Friday his country wants to allay international concerns over its controversial nuclear programme, widely suspected of hiding efforts to build a bomb. Zarif, a moderate whose ministry was tasked Thursday by President Hassan Rowhani to handle Tehran\'s negotiations with world powers, said \"there are two principles in the nuclear domain -- first and foremost, respect for our rights in matters of nuclear technology, especially the enrichment of uranium. \"Following that is to allay international concerns\" on the atomic programme.
