Pakistan polio vaccination facilities have had 2 clearly media reported stories of them being the sites of violence since mid January of this year; Quetta, and a few days ago Karachi where police were killed.
The story at this link here states in their take of elucidating the situation, that a splinter group from the Taliban feels the vaccination centers were and, or are, being used as cover for plans to cripple Bin Laden, and the prospect of a plot of 'sterilizing' children. Link:
