Terrorist infighting kills 640 in Syria: Report

Infighting between foreign-backed terrorists in Syria has left more than 640 people dead since late April, a report says.

The so-called Syrian Observatory for Human Rights documented in the report released on Friday that at least 130,000 people have also been forced out of their homes since then.

The UK-based group said Takfiri militants of the al-Qaeda-linked Islamic State of Iraq and the Levant (ISIL) were preventing food and medical supplies from reaching some neighborhoods of Deir al-Zour in eastern Syria.

The infighting has escalated over the past months amid gains by the Syrian army across the country.

Syria has been gripped by deadly violence since March 2011. Over 160,000 people have reportedly been killed and millions displaced due to the violence fueled by the foreign-backed militants.

According to reports, the Western powers and their regional allies — especially Qatar, Saudi Arabia and Turkey — are supporting the militants operating inside Syria.
