2010 Badakhshan massacre
The identity of the attackers is unknown. When news of the killings broke, both Hizb-e Islami and the Taliban initially claimed responsibility for the attack, accusing the doctors of proselytism and spying. These claims were later refuted by Taliban leaders in Nuristan and Badakhshan, who stated that they had confirmed the dead were bona-fide aid workers, condemned the killings as murder, and offered their condolences to the families of those killed.
The attack was the deadliest strike against foreign aid workers in the Afghanistan war. The killings underscored the suspicion Christian-affiliated groups face from some Afghans and government opponents and the wider risks faced by aid workers in the country. Provided by Wikipedia
