Russian Foreign Minister Sergei Lavrov has accused the US of seeking to provoke North Korea into stepping up its nuclear missile programme.

He rejected a call by the American envoy to the UN Security Council to sever ties with the North after its latest ballistic missile test.

Russia argues sanctions do not work and advocates negotiations instead.

The US has warned that North Korea’s government will be “utterly destroyed” if war breaks out.

On Wednesday, the North tested its first missile in two months, saying the continental US was now within striking distance.

However, defence experts have cast doubt on its ability to master the technology needed to launch a missile carrying a warhead capable of re-entering the Earth’s atmosphere.
