Negotiators at the Iranian nuclear talks  have failed to strike a deal as the final day of discussions begin, Reuters reported on Saturday.
Officials representing the six nations - the U.S., Russia, China, France, Germany and the U.K. - said they had little hope of finding common ground , despite Iran's positive statements in the past.
The Almaty negotiations mark the second round of talks this year. At the first round, in February, the Iranians were cautiously optimistic : "I call it a milestone. It is a turning point in the negotiations,” Iranian foreign minister, Ali Akbar Salehi told Australian broadcaster ORF at the time.
The international powers are fearful that Iran is seeking nuclear capabilities in order to produce an atom bomb , a accusation that the Persian state has always denied.
