The Islamic State of Iraq and the Levant, the radical Al Qaeda offshoot storming toward the Iraqi capital of Baghdad right now, is terrifying.
ISIL insurgents have carried out mass executions, random killings, public crucifixions, amputations and beheadings across Syria and Iraq where it wants to establish a Sunni Islamic caliphate governed under strict Sharia law.
Background about ISIL from GlobalPost: Where ISIL, the jihadist group that is seizing Iraq, came from and what it wants
ISIL is considered so extreme that core Al Qaeda moved to distance itself from it earlier this year, suggesting the group is too violent. Seriously. Iraq's security forces know: ISIL's attack on the Iraqi city of Mosul this week prompted the US-trained Iraqi soldiers to strip off their uniforms in the street and run for their lives.
Here are just some examples of ISIL's brutality.
Be warned: the images and videos are disturbing.

Members of ISIL have hung on crosses the bodies of executed rebel and government fighters in a number of cities under its control in northern Syria.
Public floggings, beheadings and amputations
ISIL, which imposes its own brand of Islamic law in the territories under its control in northern Syria and northwestern Iraq, uses barbaric methods to punish accused criminals.

This video posted on YouTube claims to show two men in Syria being flogged by a member of ISIL after they missed Friday prayers.
Arbitrary detentions and torture
Human rights groups say abductions, arbitrary detentions and torture are all strategies used by ISIL militants. The victims include people suspected of simple crimes like theft and drinking alcohol.
Former detainees in northern Syria told Amnesty International they were held in "grossly inhumane conditions," frequently flogged with generator belts and thick pieces of cable, tortured with electric shocks and had their bodies bound in excruciatingly painful poses.
Often detainees are given summary trials that sometimes last barely a minute before being taken away and killed.
This week ISIL abducted 49 members of the Turkish consulate in Mosul, bringing to 80 the number of Turkish citizens in the group's custody.
So this is what Iraq is now up against. Time to put together a new Coalition of the Willing?
