North Korean leader Kim Jong Un has returned home following a failed nuclear summit with President Donald Trump in Vietnam.

The two met in Hanoi for their second summit last week, but the high-stakes meeting ended without any agreement on how to resolve the North Korean nuclear crisis.

Both Washington and Pyongyang blame each other for the talks' breakdown. Neither side says they would pull out of diplomacy.

The North's Korean Central News Agency says Kim arrived in Pyongyang by train on Tuesday. The report didn't mention his meeting with Trump.

The North's main Rodong Sinmun newspaper previously reported that Kim and Trump had agreed to continue talks to resolve issues discussed in their Hanoi summit. The newspaper didn't mention the lack of agreement in the summit.
