IS militants release new video featuring captured British journalist

Islamic State (IS) militants have released a new internet video, where John Cantlie, a British reporter and photojournalist held captive by the group, doubts the effectiveness of US efforts, aimed at eradicating the extremists, RIA Novosti reported, citing the Daily Mail.

"Air power is good at taking out specific targets, but it is not much use at taking and holding ground," Cantlie said as quoted by the Daily Mail Monday.

"For that you need effective and disciplined troops and it is hard to see how this hotch-potch army with a long history of underperforming is going to be any form of credible infantry," the British journalist added.

Cantlie also said that that the arming of Syrian rebels with Western weapons is "largely useless," because many are sold on the black market and end up in the hands of IS fighters.

This is the third time that the IS releases a video, featuring John Cantlie, who was seized in Syria together with US journalist James Foley back in 2012. Foley and another American reporter, Steven Sotloff, were later beheaded by IS militants on camera.
