Al Qaeda-backed jihadists are hanging the bodies of executed enemies on crosses crucifixion-style in a town in Northern Syria, according to a Syrian opposition group. The executions reportedly took place Tuesday in Raqqa, where the extremist group Islamic State of Iraq and the Levant, or ISIS, an Al Qaeda-linked network, has taken over the city, according to Abu Ibrahim Alrquaoui, who identifies himself as a founder of a group called Raqqa is Being Slaughtered Silently.
