This week, Bob Woodruff reports from inside North Korea. The trip is his first visit there since 2005, when he was one of only a few journalists allowed into the DPRK (Democratic People's Republic of Korea). North Korea has acknowledged that it has nuclear weapons and says it tested one in October 2006. ABC News was denied access to a nuclear facility during Woodruff's earlier visit, but during this visit he was given rare access inside a facility.
