Murderous pens found on North Korean assassin Weapons experts said all three could kill. Authorities stopped the would-be assassin, named only as Ahn, as he was on his way to meet an anti-Pyongyang activist in Seoul, ostensibly to talk about funding his work against the North Korean regime. The activist, Park Sang-Hak, is top of North Korea's hitlist - having angered Pyongyang by sending leaflets across the border via balloons. Park was shocked when shown the lethal stash hidden on Ahn's person "I didn't believe they'd try and kill me on the crowded streets of Seoul," he told CNN. He has said he will keep on protesting the regime despite the threat to his life.
