Approximately 400 foreign fighters have joined the Kurdish People's Protection Units (UPG) in Syria to fights against the ISIL terrorist group, the Syrian Observatory for Human Rights said.

The YPG, which has been fighting against the ISIL in Hasaka, Raqqa and Aleppo provinces, has been recruiting many of its foreign fighters through Facebook since last year.

Recruits have joined the YPG from Europe, Australia, North America and South America.

The ISIL Takfiri terrorists currently control shrinking swathes of Syria and Iraq. They have threatened all communities, including Shiites, Sunnis, Kurds, Christians, Ezadi Kurds and others, as they continue their atrocities in Iraq.

Senior Iraqi and Syrian officials have blamed Saudi Arabia, Qatar, and some Persian Gulf Arab states for the growing terrorism in their country.

The ISIL has links with Saudi intelligence and is believed to be indirectly supported by the Israeli regime.
