This photo, taken on February 10, 2018, shows Kim Yo-jong, North Korean leader Kim Jong-un's sister (L) and Kim Yong-nam, the North's ceremonial head of state (R), joining a dinner hosted by Unification Minister Cho Myoung-gyon in Gangneung, the sub-host city of the Olympics.
Numerous protestors carried American flags, and one carried a banner making a direct plea to President Donald Trump.

Earlier in the day, Kim Yo-jong, as the North ruler's special envoy, delivered his letter to President Moon Jae-in, which includes an invitation of the South's leader to Pyongyang at an early date.
"The fact that we are here together will mark the precious start of our first step toward global peace", Moon said.

The highest profile member of the North Korean delegation to the Games, she is the first immediate member of the North's ruling family to visit the South since the 1950-1953 Korean war.
White House officials stressed that Pence had applauded only for the American team, but Asia experts said the vice president's refusal to stand could be seen as disrespectful to the hosts.
The North Korean delegates later Saturday may attend the debut of the first-ever inter-Korean Olympic team at the women's ice hockey tournament in Gangneung.
The games have turned into an opportunity to cool tensions between the two Koreas, after initial doubt that North Korea would participate at all. They may also see a performance by a visiting North Korean art troupe in Seoul on Sunday before flying back to Pyongyang.
