A new photo report purportedly put out by the Islamic State shows 2 young men before they perpetrated a suicide bombing against Iraqi forces in "Wilayat Salahuddin," Iraq. The photo report was released on ISIS terrorist channels on November 6. An accompanying summary about the photos reads: "The Istishhadi Brothers Who Raided Rafidi Security Forces in #Tikrit and a Gathering of #Rafidi Mushrikin in #Samarra." "Istishhadi" is plural for the Arabic "istishhad," meaning "'martyrdom', 'death of a martyr', or 'heroic death.'" "Rafidi" is a derogatory term for Shia Muslims used by Sunnis. It means "rejectors" because Shia Muslims believe in a different line of successorship for Islam following the death of its founder Muhammad. It is commonly used to refer to the Shia government forces of Iraq, and sometimes Iran as a whole. Tikrit and Samarra are cities north of Baghdad, with Tikrit infamously being the hometown of Saddam Hussein, deposed and deceased President of Iraq. One day ago, The Independent reported that two suicide bombers used ambulances loaded with explosives to kill at least 21 people and wound many more in Samarra and Tikrit. The BBC reports that in Samarra, the target was "the al-Askari mosque - one of the holiest shrines in Shia Islam. Iranian pilgrims were among the dead." As Iraq government forces continue to advance in Mosul, more attacks around Iraq are expected to be committed by fleeing Islamic State terrorists.
