The Britons signing up for Jihad

When Ifthekar Jaman, from Portsmouth, arrived in Syria in 2013 and began posting images of himself posing as a jihadist fighter – and, somewhat bizarrely, occasional pictures of cats – he seemed something of an exception.

Here was a 23-year-old who had arrived in the middle of an increasingly internecine conflict, saying it was his duty to take up arms because he saw Muslims being slaughtered.

Two years on, he is dead – and we now know how far from an exception he was.
