North Korea issues a dire warning on the US-South Korea deterrence agreement.

Kim Yo-jong, the sister of North Korean leader Kim Jong-un, has warned that a recent US-South Korean deal will lead to a "more serious danger". The US agreed to deploy nuclear-armed submarines to South Korea and involve Seoul in its nuclear planning to counter nuclear threats from the North. In return, South Korea agreed to not develop its own nuclear weapons. The Washington Declaration was announced this week during President Joe Biden's talks with his South Korean counterpart Yoon Suk-yeol in the American capital. Ms Kim holds a senior position in the Central Committee of the Workers' Party of Korea and is reported to have influence on her brother.

President Biden hailed the deal, saying it would strengthen the allies' co-operation in deterring a North Korean attack. President Yoon said the agreement marked an "unprecedented" commitment by the US to deter attacks and protect allies by using nuclear weapons. China warned against "deliberately stirring up tensions, provoking confrontation and playing up threats".
