Update with more detail: The Washington Post published this more detailed account of what happened here.
The International Rescue Committee has released the names of its four staff members who were tragically killed in an ambush Wednesday morning in Logar Province Afghanistan.
It doesn’t matter to Islamic fighters whether westerners are good people doing charitable work. I suspect the women in this group were targets because they symbolize freedom for women—something the Taliban and Al-Queda fear the most.
The victims were en route to Kabul and traveling in a clearly marked International Rescue Committee vehicle when they came under fire at mid-morning.
The IRC has suspended operations in Afghanistan indefinitely according to this report.
