US Secretary of State Mike Pompeo has dismissed accusations by North Korea that he engaged in “gangster-like” behaviour during a visit there.

After two days of talks with senior officials, he said efforts to push Pyongyang towards abandoning nuclear weapons had international backing.

He stressed that denuclearisation was a condition for lifting sanctions.

It was Mr Pompeo’s first visit to the North since last month’s summit between Kim Jong-un and President Donald Trump.

The North Korean leader says he is committed to denuclearisation, but how this will be achieved is unclear.
