North Korean leader Kim Jong-un has said he would take part in a third summit with Donald Trump - but only if the US brought the "right attitude".

North Korean state media reported the comments by Mr Kim on Saturday.

In a speech, he urged Mr Trump to pursue a deal that was "fair" and "mutually acceptable" to both nations.

The two leaders met for the first time in Singapore last year. However, a second summit in Hanoi in February broke down over denuclearisation steps.

Mr Trump said North Korean officials had wanted economic sanctions lifted in their entirety in exchange for disabling a major nuclear site, provoking him to walk away.
