In advance of President Bush’s speech, Iraqi PM Nouri al-Maliki has (very) belatedly told the Shi’ite militias to disarm or face an all-out assault.

BAGHDAD, Iraq - Iraq’s prime minister has told Shiite militiamen to surrender their arms or face an all-out assault by U.S.-backed Iraqi forces, senior Iraqi officials said Wednesday, as President Bush said he will commit an additional 21,500 American combat troops to the war.

Under pressure from the U.S., Prime Minister Nouri al-Maliki has agreed to crack down on fighters controlled by his most powerful political ally, Muqtada al-Sadr, a radical Shiite cleric, according to officials. Previously, al-Maliki had resisted the move.

“Prime Minister al-Maliki has told everyone that there will be no escape from attack,” a senior Shiite legislator and close al-Maliki adviser said. “The government has told the Sadrists: ‘If we want to build a state we have no other choice but to attack armed groups.’”
