The nuclear test conducted by North Korea during the night is a serious act that grievously undermines peace and security in Asia and worldwide.
I condemn in the strongest possible terms this latest provocation by a regime that bears responsibility for destabilizing an entire region.
North Korea is continuing to develop a nuclear and ballistic arsenal in gross violation of UN Security Council resolutions. This escalation is unacceptable.
A swift and strong reaction by the UN Security Council, the European Union, and the entire international community is called for. I will be in close touch with my counterparts to ensure the unity of our joint effort.
