Social media imagery uploaded this week of Iran-backed Iraqi and Palestinian fighting forces allied with Syrian Arab Republic:
Iran-backed Kata'ib Sayyid Al-Shuhada fighting force members pose before just-visible dome on the shrine of Sayyidah Zainab near Damascus, Syria. Note the unfurled Iraqi national flag.
It appears to be a customary refrain for Iran-backed Shia fighting forces to claim "in defense of the shrine of Sayyidah Zainab," in similar manner to the culturally dissimilar refrain of American fighting forces waging war "in defense of freedom."
