Islamophobia has been an ongoing concern in the west since 9/11, but a number of recent incidents in Britain have given rise to a new wave of hatred that experts say is finding a breeding ground online.
Part of the problem, researchers say, is that right-wing groups can post anti-Islamic comments online without fear of legal prosecution.
"If they were to say, 'Black people are evil, Jamaicans are evil,' they could be prosecuted," says Fiyaz Mughal, founder of Islamophobia reporting web site TellMamaUK.org.
