UN Secretary-General Antonio Guterres has expressed disappointment after the 11th Review Conference of the Nuclear Non-Proliferation Treaty ended without consensus, calling it a missed opportunity to make the world safer, Al Jazeera reports.

In a statement delivered by his spokesman, Stephane Dujarric, Guterres said he welcomed the engagement of member states but regretted that the conference fell short, “especially at a time of such pressing challenges that threaten international security”.
