A team of American diplomats involved in preparatory discussions ahead of a potential summit between President Donald Trump and North Korean leader Kim Jong Un have left a hotel in Seoul amid speculation that they are resuming the talks.

It wasn't immediately clear whether the American officials including Sung Kim, the U.S. ambassador to Manila, were heading Tuesday to the border village between the Koreas where they met with North Korean officials on Sunday.

Trump withdrew from a planned June 12 Singapore summit with Kim last Thursday citing hostile North Korean comments, but has since said the meeting could still happen. South Korean President Moon Jae-in met with Kim on Saturday in an effort to keep the meeting alive.
