"The tenth set of agents---two men known as Team Q---headed into the kingdom of Bhutan. [...] Then in April 1964, the country's prime minister was killed by unknown assailants. Coincidentally, this happened at the same time Team Q was crossing the border, sparking unfounded rumors that the Tibetans were attempting to overthrow the kingdom. As the rumors escalated into diplomatic protests, the two agents were quietly withdrawn, and Bhutan was never again contemplated as a launch site" (for CIA agent infiltration into bordering Tibet)
