The International Atomic Energy Agency (IAEA)'s chief said on Tuesday he is still hopeful for a deal between Iran and world powers to revive the 2015 nuclear pact but that talks were struggling and the moment could be lost.
"We are, of course, still hopeful that some agreement is going to be reached within a reasonable time frame, although we have to recognize the fact that the window of opportunity could be closed any anytime," IAEA Director General Rafael Grossi said, speaking to European Parliament committees via webstream.
