North Korea: Kim Jong-un's sister warns US not to 'cause a stink'

The influential sister of North Korean leader Kim Jong-un has warned the US not to "cause a stink", as President Joe Biden prepares to set out his Korean policy.

In remarks on state media, Kim Yo-jong criticised the US and South Korea for conducting joint military exercises.

Her comments come a day before top US officials are due to arrive in Seoul.

The US government has said it has been trying for weeks to make diplomatic contact with North Korea.

Pyongyang has yet to acknowledge that President Biden is now in office.

The two countries remain at loggerheads over the North's nuclear and ballistic missile programmes.
