"Az-Zaman, Iraq daily newspaper, reported that Ayatollah Ali Al-Sistani refused to interfere in the dispute over the nomination of a prime minister for the next four years. According to the paper, Sistani's deputy in Karbala asked the groups within the United Iraqi Alliance (UIA) to remain united if they want to keep his blessings. The paper added that the situation in Najaf, where the four grand Ayatollahs reside, is full with apprehension. Militia men from Al-Mahdi Army loyal to Moqtada Al-Sadr and others from the Supreme Council (SCIRI) loyal to the Hakim family took their positions on the streets of the city in case of any escalation."

Nice try to push the blame on the bombings to the Wahabi terrorist, terrorist that you have in the past denied even existed, much less could pull off an attack like the ones we have seen in the very heart of Shi'a power. This is Shi'a on Shi'a violence and I think all can see that.
