18 fighters from Liwaa Al Tawhid killed by ISIS's silencer guns

 18 fighters from Liwaa Al Tawhid have been killed by the State of Iraq and al-Sham's silencer guns in their sleep on Sunday in Aleppo, pro-ISIS social media pages said.

 "Iraqi Sahwat war experience came to Syria," ISIS said in statement posted by ‘The Victorious Party In the Land of Ash-Sham’ Facebook page. Al-Qaeda splinter group recently used to dub the Islamist rebels as “Sahwat” in reference to the Iraqi tribal forces that involved in combating al-Qaeda.

ISIS said that killing Liwaa at-Tawhid fighters was for the revenge of "the raping of ISIS women members by Tawhid men during the blitzkrieg attacks on ISIS bases."

ISIS source claimed on January 5 2014 that Iraqi militants with silencer guns had entered Aleppo month ago "with experience in fighting Sahwat."

More than 1,800 people, mostly fighters, died in January fighting between rebels and ISIS, since three massive rebel alliances declared war against ISIS month ago.

Deir al-Zour considers as a key conduit for ISIS to send weapons and fighters from Iraq into Syria.

 Syria's nearly three-year conflict began as popular protests against four decades of Assad family rule but changed into armed insurgency under a security force crackdown.

Now the major Arab state is in a full-scale civil war that has killed more than 136,000 people and forced over 6 million - more than a quarter of the population - to flee their homes.
