Six countries from the Americas say they are asking the International Criminal Court to investigate Venezuela's government for alleged crimes against humanity. It's the first time that member countries have referred another country to the Netherlands-based U.N. court.

Argentina, Peru, Colombia, Chile, Paraguay and Canada made the announcement on the sidelines of the U.N. General Assembly meeting.

The court has already opened a preliminary investigation into allegations that since April 2017 Venezuelan government forces "frequently used excessive force to disperse and put down demonstrations," and abused some opposition members in detention.

Wednesday's move could broaden the scope of the existing preliminary probe. The countries accuse Venezuela of several crimes including murder, torture and unjust imprisonment.

U.S. Secretary of State Mike Pompeo says his meeting with North Korean Foreign Minister Ri Yong Ho was "very positive."

Pompeo made the comment on Twitter on Wednesday after meeting with Ri at the U.N. General Assembly. The meeting comes as U.S. President Donald Trump and North Korean leader Kim Jong Un work to set up a widely expected second summit to restart stalled diplomacy meant to rid the North of its nuclear weapons.

Pompeo said that "much work remains, but we will continue to move forward."

Kim made denuclearization vows last week in a summit with the South Korean president in Pyongyang, but there's still skepticism over his sincerity to relinquish weapons that many believe are the only major guarantee of his continued authoritarian rule.
