Radical 'ISIL' militants kill 70 prisoners, 300 escape

More than 300 prisoners in the Islamic State of Iraq and the Levant’s chambers have been escaped while 70 other prisoners have been killed in ISIL’s main headquarters in Kadi Askar in Aleppo. 

The tragic massacre has been committed few hours before Syrian rebel brigades taking control of the headquarters of the ISIL, according to sources.

“Al Qaeda radicals have committed the second massacre in two days, killing tens of abductees from media activists and rebel fighters,” activists said.

Journalists Milad al-Shihabi and Ahmed Brimo were freed from ISIL’s prison in Childern Hospitan in Aleppo, according to Brimo’s family.

ISIL has been fighting a coalition of moderate and Islamist rebels angered by a spate of abuses by the jihadists, who have been accused of kidnapping and killing civilians and rival rebels.

Late Tuesday, an ISIL spokesman said the group would "crush" opposition fighters and warned that it considered members of the opposition National Coalition and the military command of the Free Syrian Army to be "legitimate targets."

ISIL has been accused of horrific abuses in areas where it operates, and also of seeking hegemony by taking key roads and checkpoints from its rivals.

Some Assad opponents have even accused it of serving regime interests.

Since Friday, along with the Syrian Revolutionaries Front and the nascent Mujahedeen Army, the Islamic Front has been engaged in fierce fighting with ISIS in rebel-held areas.

The latest clashes broke out Friday after residents accused ISIS members of killing a doctor in Syria’s northern province of Aleppo.

The focus of combat has been in opposition areas in Aleppo and Idlib provinces, but Sunday spread to Hama and Raqqa provinces.

ISIL is considered one of the most extremist and intolerant groups currently involved in the fighting against Bashar Assad, even in comparison to the other rebel group linked to al-Qaeda, Jabhat al-Nusra.

The group’s gains have underscored growing infighting among rebel factions seeking to oust Assad. A recent takeover of opposition warehouses by ISIL members spurred the US and UK to announce they would suspend the nonlethal aid they had been providing to Syrian rebels.

Syria's armed uprising began as a series of peaceful democracy protests 33 months ago but escalated into a full-blown civil war after Assad's regime launched a brutal crackdown on dissent.

The conflict is estimated to have killed around 130,000 people and displaced millions more.
