The group has released several joint statements with other groups such as Islamic Resistance Movement and the Islamic Front for the Iraqi Resistance, which are known to be of an ikhwan background. In one of these joint statements, six groups (including the IAI) called for Iraqis to participate in the referendum on the October 2005 constitution by voting against it. (This was in conspicuous contrast to al-Qaeda in Iraq, which said that simply participating in voting is a compromise of the fundamentals of Islam, even if one were to vote against it.)
