From the New York Times:
PESHAWAR, Pakistan — Six Pakistani employees of the American Christian charity World Vision were gunned down Wednesday, and seven others were wounded in an attack on the aid group’s offices in a remote village in northern Pakistan.
Pakistani authorities said about a dozen masked militants stormed the building at about 9:30 a.m., pulled the staff members out of their offices and herded them into a single room, then started shooting indiscriminately. The attackers set off a bomb as they left, destroying the offices, which are located in North-West Frontier Province, in the village of Oghi, near the disputed region of Kashmir. [...]
World Vision is among the largest Christian charities in the world, and says it has thousands of staff members working in almost 100 countries on projects related to disaster relief, development, health and other issues. It is among many international aid groups that have had operations in northern Pakistan since October 2005, when a devastating earthquake killed thousands.
