The fugitive Salah Abdeslam had a suicide belt on after the Paris attacks, a lawyer for one of the men who drove him to Belgium has told Belgian TV.

Others have been stoking fears that the wave of refugees trying to escape the horrors of war and oppression in Syria is really just a Trojan horse for the passage of travelling jihadists. 

"We wouldn’t blame all Americans for the past actions of the Ku-Klux Klan. But it seems some people have no problem judging every woman riding the tube in a hijab to be a terrorist."
