A North Korean assassin's toolkit of death was revealed this week after the would-be killer tried to murder an activist in 2011.
The first, a toxic weapon disguised as a Parker ballpoint pen, contains a poison needle that can paralyze and suffocate its victim within minutes of the first prick. The second is a similar pen that shoots a toxin-filled bullet, and the third is a flashlight loaded with up to three bullets and is capable of firing accurately.
All of the items are deadly and almost impossible to identify as weapons, CNN learned.
