Trump vows to maintain 'maximum pressure' on North Korea

North Korea state media say Friday's summit with South Korea paves the way for a new era of peace and prosperity.

But US President Donald Trump is vowing to maintain maximum pressure on Pyongyang until it gives up its nuclear weapons.

His comments follow a historic declaration of peace from the North and South Korean leaders on Friday.
