Why are Palestinians of Yarmouk ignored compared to those in Gaza?

The slaughter of Iraqi soldiers will be reinforced by the deepening humanitarian disaster in Syria’s Yarmouk Palestinian refugee camp, which has, since the start of the Syrian civil war, been caught in the vicious battle between the government forces of Bashar al-Assad and the revolutionaries of the Free Syria Army.
This threatens the existence of the Palestinian community. The jihadists of Isil are attempting to obliterate the social, religious and cultural fabric of the residents, by forcing, on pain of death, Islamic Sharia on them. The community has remained resolutely Palestinian through the generations by consistently pledging allegiance to Fatah, Hamas and the Popular Front for the Liberation of Palestine (PFLP).
