The most interesting reaction so far to the destruction of the minarets at the Samarra mosque -- the same one that sparked intense Sunni-Shia killings in 2006 -- is Muqtada Sadr's reaction: He called for reconciliation with the Sunnis. From the Post:

Sadr called for peaceful demonstrations, and reconciliation within Iraq's warring factions, to mark the minarets' destruction. "We declare a three-day mourning period . . . and shout Allahu Akbar (God is greater) from Sunni and Shiite mosques," Sadr said in a written statement, declaring that no Sunni Arab could have been responsible for the attack on the Shiite shrine.

Instead, he faulted the Iraqi government for failing to protect the landmark, and blamed the relentless violence in Iraq on the ongoing U.S. military presence.

Sadr also announced that his 30 members of parliament were suspending their membership in that body until the government of Iraq takes steps to rebuild the shrine. It's been in ruins for more than a year.

The Times notes that the U.S. and Iraqi governments this week decided to replace the guards, mostly Sunnis, with Shia forces:

Speaking on Al Jazeera television, Abdul Sattar Abdul Jabbar, a prominent Sunni cleric, said the new guards had arrived at the shrine shouting sectarian slogans that may have provoked local Sunnis, in a sign that the attack was already being depicted as sectarian.

Prime Minister Maliki, of course, is already blaming "supporters of Saddam Hussein" for the attack. He imposed an indefinite curfew in Baghdad.
