South Korean police detained 19 students on Friday after several climbed over the wall into the grounds of the U.S. ambassador's residence in Seoul in protest against the U.S. troop presence in the country.
The group, which identifies itself as a coalition of progressive university students, posted photos on its Facebook account in which several members used ladders to climb over a wall surrounding the home of Ambassador Harry Harris.
In a separate video, apparently broadcast from inside the compound, they accused the United States of demanding a 500 percent increase in the cost of keeping some 28,500 troops in South Korea, holding a banner saying, "Leave this soil, Harris!"
