In other Iraq news, the Iraqi government announced Tuesday the dismissal of its two senior police commanders. The two officials led Iraq’s special police commandos and its public order brigade. The units have come under scrutiny over allegations they’ve been heavily infiltrated by Shiite militias. The firings come as Iraqi Prime Minister Nuri al-Maliki is facing intense pressure from US officials. The White House has disclosed Maliki even asked President Bush during a conversation Monday if the administration is planning to replace him.
