Revenge for the death of Shamzai. From ABC News, with thanks to JJP Mackie:
KARACHI, Pakistan May 31, 2004 —
A bomb ripped through a
Shiite Muslim mosque in Karachi during evening prayers Monday, killing
at least 16 people and wounding 38 others. A top Pakistani official
said the blast could be revenge for the assassination of a senior Sunni
cleric.
Shamzai was a cleric who supported the Taliban.
Much of Karachi's violence is blamed on Islamic militants,
angered by Musharraf's support for the U.S.-led campaign against
terrorism in Afghanistan, but clashes between rival Sunni and Shiite
Muslims are also common.
Much has been made of Sunni versus Shiite tensions, but many Sunni
jihadis were inspired by the Shiite Islamic revolution in Iran.
In 1979 we were immediately told, of course, that Khomeini
represented (all together now) only a tiny minority of extremist
Muslims.
