– Foreign Secretary William Hague
UN Security Council Resolution 2087 committed the Security Council to take significant action in the event of a further launch or nuclear test by North Korea.
The UK will begin urgent consultations with Security Council partners calling for a robust response to this latest development.
North Korea has a choice to make: it can either engage constructively with the international community, cease developing its nuclear and ballistic missile programmes and return to negotiations, or face increasing isolation and further action by the Security Council and the international community.
The United Nations says it "strongly condemns" North Korea's nuclear test. The United States is calling for an increase in sanctions against the communist state.
