MOSCOW (Sputnik)�� The UN chief said that he called on�world leaders to�be committed to�this accord. "I believe that this agreement by�P5+1� that was a robust agreement� We have to�respect this agreement. I have been discussing this matter with�Iranian authorities and they are also concerned that� if there are any changes or any disruptions of�the process of�this agreement then it will take much-much longer time [to implement the deal]. During that time, who knows what will happen again," Ban told the CNN broadcaster in�a Tuesday interview, which was dedicated to�the forthcoming end of�the official's tenure.
