Making a nuclear weapons test ban treaty a reality represents “low hanging fruit” in the effort towards halting rising tensions over the Korean Peninsula.

That’s according to Lassina Zerbo, Executive Secretary of the Comprehensive Nuclear Test-Ban-Treaty Organization (CTBTO).

He’s been attending the opening week of the new UN General Assembly, where North Korea’s continuing violation of Security Council sanctions in pursuit of its nuclear weapons programme has been a main diplomatic issue.

Since the treaty opened for signature, only three countries have conducted nuclear tests, with the DPRK the only one to have done so this century.

Cristina Silveiro asked Mr Zerbo what his objectives were for the week at UN Headquarters.
