A banner to pay tribute to the victims of the Paris attacks is seen on the facade of the city hall in Alencon, France, November 25, 2015. The voice claiming Islamic State's responsibility for the deadly Paris attacks is known to many in the small French provincial town of Alencon. To family, Fabien Clain was a "big teddy bear", to neighbours he was polite, and at the local mosque, he was a fellow worshipper who came to pray. To the authorities, he was a veteran jihadhi jailed in the past for recruiting militant fighters and believed to have fled to Syria this year, and who may have played a wider role in the Nov. 13 violence, the worst in France since World War Two.
