There are organizational as well as ideological ties that bind Sunni sectarians, Arab and Asian alike, with Sunni Arab extremists. While outside the Muslim world the violent anti-Westernism of the Taliban and al-Qaeda appears most prominent, there can be no question that intense hatred of Shias and Shiism is an important motive for both these Sunni terror groups. The Taliban, al-Qaeda, and various Pakistani Sunni extremists fought side by side during the Afghan internal strife of the 1990s. Indeed, most of the murders of Shias at Mazar-i Sharif and Bamiyan appear to have been committed by Pakistani killers from Sipah-i Sahaba, who nearly started a war with Iran when they overran the Iranian consulate in Mazar-i Sharif in 1998 and slaughtered eleven diplomats.
