			 Douglas is one of a growing band of foreigners to dodge 
			authorities and join the fight against Islamic State militants who 
			have killed thousands and taken vast parts of Iraq and Syria, 
			declaring a caliphate in territory under their control. 
 Many of these fighters argue they are there for humanitarian reasons 
			but they say their decision to take up arms to fight for the Syrian 
			people will not be viewed as such by some.
 
 "I want to fight the Islamic State, although it might be the last 
			thing I do," said Douglas, 66, from Vancouver, as he prepared to 
			board a boat crossing a remote stretch of the Tigris River .
 
 "I know I have 10 years to live before I will start develop dementia 
			or have a stroke so I wanted to do something good," he added, 
			although he acknowledged that taking up arms was new on the list of 
			jobs and occupations he has previously pursued.
 
 So far an estimated few dozen Westerners have joined Kurdish 
			fighters battling Islamic State in northern Syria, including 
			Americans, Canadians, Germans, and Britons.
 
 The Syrian Kurdish armed faction known as the YPG has not released 
			official numbers confirming foreign or "freedom fighters" and 
			academics say it's hard to assess the total.
 
			 But the number pales compared to an estimated 16,000 fighters from 
			about 90 countries to join Islamic State since 2012, according to 
			the U.S. Department of State figures.
 The United Nations has warned extremists groups in Syria and Iraq 
			are recruiting foreigners on an "unprecedented scale" and with a 
			commitment to jihad who could "form the core of a new diaspora" and 
			be a threat for years to come.
 
 FIGHTING FOR A CAUSE?
 
 Western governments are closely monitoring foreign fighters but law 
			enforcement agencies are acting differently towards those joining 
			Islamic State or those linking up with the Kurdish resistance whose 
			motivations are far more diverse.
 
 British Prime Minister David Cameron has made it clear there is a 
			fundamental difference between fighting for the Kurds and Islamic 
			State. British law stipulates fighting in a foreign war is not 
			automatically an offense and depends on circumstances.
 
 Two British military veterans, Jamie Read and James Hughes, returned 
			to England last month after several months with the YPG, saying they 
			were fighting for "humanitarian purposes", and no action has been 
			taken against them on their return.
 
 They signed up outraged by a series of chilling videos showing the 
			murders of two U.S. journalists, a U.S. aid worker, and two British 
			aid workers and by the plight of millions of Syrians caught between 
			Islamic State and government forces.
 
 British-based monitoring group, the Syrian Observatory for Human 
			Rights, estimates in six months the radical Sunni group has killed 
			about 1,878 people in Syria off the battlefield, mostly civilians.
 
 More than 200,000 people have been killed in the Syrian civil war, 
			which started when President Bashar al-Assad's forces cracked down 
			on peaceful pro-democracy protests in 2011.
 
 "We went there to help innocent people and to document the YPG 
			struggle against ISIS," Hughes, 26, who spent five years in the 
			British army, told the Thomson Reuters Foundation.

			"We had a warm welcome home. Everybody thought we were heroes. They 
			were proud of us. I also received hundreds of messages of people 
			wanting to join the YPG," he said, adding he planned to return to 
			Syria in coming months.
			 
			Still many foreign YPG fighters are concerned about legal 
			repercussions when they return home so seek to stay anonymous. "We 
			might get in trouble with our governments," said one U.S. veteran 
			who ensured all his financial and legal affairs were in order before 
			heading to Rojava, the area controlled by the YPG in Syria.
 Many are concerned how the media portrays them at home and wanted to 
			clarify they are volunteers, not mercenaries. They say they are not 
			paid but are there as they believe in the cause.
 
 Many have some military experience and have signed up to the battle 
			through contacts on Facebook.
 
 Lorenzo Vidino, an analyst at the Institute for the International 
			Political Studies in Italy, said foreign fighters might argue they 
			are joining the battle against Islamic State for the good but they 
			were not effective militarily.
 
 "Westerners joining the YPG are a very small phenomenon especially 
			if compared to Islamic State. The IS recruitment machine works 
			better and you can see evidence of that in terms of numbers," he 
			told the Thomson Reuters Foundation.
 
 U.S. fighter Dean Parker, 49, joined after watching video footage of 
			the blitz on Sinjar in northwest Iraq in August when Islamic State 
			militants killed or captured thousands of minority Yazidis.
 
 "I saw the fear and terror on this child eyes who was looking 
			directly at me through the camera ... I never been moved by anything 
			like that in my life," he said in an email exchange, one of several 
			foreign fighters from Syria interviewed on location, by email or by 
			phone in November and December.
 
 Canadian-Israeli woman Gill Rosenberg, 31, from Tel Aviv, said in a 
			recent interview with Israel Radio that she decided to join the YPG 
			for humanitarian and ideological reasons.
 
 
			 
			But not all foreign fighters are motivated by the same cause.
 
 Jordan Matson, 28, a U.S. army veteran from Winconsin who joined the 
			YPG about four months ago, said he joined because he was running 
			away from a "civilian" life he didn't really like.
 
 "Here, instead, everything makes sense," he told the Thomson Reuters 
			Foundation in a YPG base near to Derik, a town in Syria's 
			northeastern Kurdish region.
