553 killed since the beginning of coalition air strikes on Syria

Rose to 553, the number of people who were killed since the U.S led coalition air strikes started in Syria in the 23rd of September to the 22nd of October .

the dead included 32 civilians ( 6 children and 5 women ) were killed by coalition air strikes around oil fields in al-Hasakah, Aleppo, Idlib and Der-Ezzor countrysides.

57 fighters from Jabhat al-Nusra in the western countryside of Aleppo and north of Idlib.

464 fighters from the IS ( most of them were Non-Syrian fighters ) killed by coalition air strikes on their HQs and around oil fields in Homs, Aleppo, Hasakah, Hama, al-Raqqa and Der-Ezzor .

we in SOHR believe that the real number of casualties in the IS is larger than the number which we could document, due to the extreme secrecy by ISIS on its casualties and the difficulties to reach to thus areas . 

worth to mention that the coalition air strikes targeted many oil fields in the countrysides of Der-Ezzor, al-Hasakah, and al-Raqqa, led to material damages and devastated oil refineries belongs to civilians, what caused a significant rise in oil prices.
