Now we hear reports of former Hamas fighters from Gaza, going to Syria to fight the Assad Regime. They are "former Hamas" fighters because the organization is officially trying to distance itself from the conflict, but as the article below tells us "in keeping with the popular mood" these "former Hamas" fighters are still celebrated by Hamas as martyrs when they are killed in Syria.

The fighter had previously belonged to the armed wing of Hamas, the Izz el-Din al-Qassam Brigades.
In keeping with the popular mood, Hamas celebrated him as a "martyr" after news emerged of his death.
However the movement between Gaza and Syria is not just in one direction.
Dozens of Syrian refugees have headed here since the war started, as well as hundreds of Palestinian refugees who were living in Syria. More...
