The BBC reports that the Taliban razed the town of Bamiyan before they retreated from it this weekend. There are also reports that they executed hundreds of men in the area. The BBC doesn’t provide the full context involved here. Bamiyan and the surrounding region are populated by Hazaras, who are Shiite Muslims and who have had a long ongoing feud with the Taliban. The last time Mazar-i-Sharif fell to the Northern Alliance, Hazara soldiers summarily executed thousands of Taliban troops. It’s just this sort of sectarian violence that will work against future stability in Afghanistan.
