Photos of US ambassador to South Korea Mark Lippert meeting with the country's leaders have emerged for the first time since the envoy was attacked by a knife-wielding pro-North Korean activist. Lippert is recovering at Severance Hospital in Seoul, and was able to meet with US Navy Admiral James Winnefeld as well as members of South Korea's ruling and opposition parties.
