The UK has seen a steady increase in Islamic terrorist activity over the past two decades, according to a controversial think-tank. The right-wing Henry Jackson Society has published a thousand-page report on terrorism in the country. It examines all terror convictions related to Islamism in the UK between 1998 and 2015. It claims that between 2011 and 2015, there were 11 times more acts of terrorism, than in the preceding 13-year period. <br /><br />RT LIVE http://rt.com/on-air<br /><br />Subscribe to RT! http://www.youtube.com/subscription_center?add_user=RussiaToday<br /><br />Like us on Facebook http://www.facebook.com/RTnews<br />Follow us on Twitter http://twitter.com/RT_com<br />Follow us on Instagram http://instagram.com/rt<br />Follow us on Google+ http://plus.google.com/+RT<br />Listen to us on Soundcloud: https://soundcloud.com/rttv<br /><br />RT (Russia Today) is a global news network broadcasting from Moscow and Washington studios.
