<p>A surge in activity from Nigerias Islamist insurgency Boko Haram  now the worlds deadliest terrorist group  and Islamic State in Iraq and Syria has driven an 80% increase in the number of people killed by terrorists in 2014, <a href="http://www.visionofhumanity.org/sites/default/files/English%20Media%20Release%20GTI%202015.pdf">this years Global Terrorism Index showed</a>. In total, 32,658 people were killed in terrorist attacks in 67 countries last year, according to the index, released on Tuesday by the <a href="http://economicsandpeace.org/">Institute for Economics and Peace </a>(IEP).</p> <p>The world is reeling from <a href="http://www.theguardian.com/world/paris-attacks">the terrorist attacks in Paris last Friday</a>, which killed at least 129 people. But the index showed that 80% of last years terrorist killings were carried out in just five countries: Iraq, Nigeria, Afghanistan, Pakistan and Syria.</p> <aside class="element element-rich-link element--thumbnail"> <p> <span>Related: </span><a href="http://www.theguardian.com/global-development/2015/oct/29/afghan-exodus-grows-taliban-gain-ground-refugees">Afghan exodus grows as Taliban gains ground and hope for future diminishes</a> </p> </aside>  <p>We can see the trauma [terrorist attacks] create in the west, but think how much trauma they create in all these other countries in the world, said Steve Killelea, executive chairman of the IEP.</p>  <figure class="element element-embed" data-alt="Countries with most terrorist deaths, 2014">  <iframe src="https://charts.datawrapper.de/frtMw/index.html" frameborder="0" allowtransparency="true" allowfullscreen="allowfullscreen" webkitallowfullscreen="webkitallowfullscreen" mozallowfullscreen="mozallowfullscreen" oallowfullscreen="oallowfullscreen" msallowfullscreen="msallowfullscreen" width="460" height="580"></iframe> </figure>  <p>The index showed a close link between terrorism and people being forced to flee. Of 11 countries with more than 500 deaths from terrorism, 10 had the highest levels of refugees and [internal] migration in the world, the index said.<br /></p> <p>The sharp rise in terrorist activity noted in the report is fuelling migration out of areas controlled by Isis and into neighbouring countries. According to figures from the UNs High Commissioner for Refugees, <a href="http://www.unhcr.org/pages/49e486426.html">369,904 people have fled Iraq</a> and and <a href="http://data.unhcr.org/syrianrefugees/regional.php">4.29 million have fled Syria.</a></p> <p>Theres a strong relationship between terrorism and ongoing conflict. What were seeing is people are fleeing the conflicts, and so actually tackling the conflicts and terrorism are one and the same, Killelea said.<br /></p> <p>Terrorism makes meeting development targets, such as increasing access to education and improving water and sanitation, impossible, Killelea said. After getting a solution to the conflict, then you can come back and address the underlying developmental causes. A lot of the time theyre related back to the reasons for the conflict in the first place.</p> <p>Boko Haram is now the worlds most deadly terrorist group after it claimed 6,644 killings last year, a 317% increase from 2013.<br /></p> <p>Bombings and gun attacks carried out by Isis in Syria and Iraq and Boko Haram in Nigeria caused 12,717 deaths. Taliban insurgents in Pakistan, Fulani militants in Nigeria  who attack mainly Christian farming communities in northern and central Nigeria  and al-Shabaab fighters in Somalia all killed more than 1,000 civilians last year, the index showed. Fulani militants carried out their deadliest attack in April 2014, opening fire on a community meeting in Zamfara state, killing at least 200 people, the report said.</p> <p>There are about 530 terrorist groups around the world, with 33 emerging last year, Killelea said.</p>  <figure class="element element-embed" data-alt="Deadliest terrorist groups, 2014">  <iframe src="https://charts.datawrapper.de/QRrII/index.html" frameborder="0" allowtransparency="true" allowfullscreen="allowfullscreen" webkitallowfullscreen="webkitallowfullscreen" mozallowfullscreen="mozallowfullscreen" oallowfullscreen="oallowfullscreen" msallowfullscreen="msallowfullscreen" width="460" height="270"></iframe> </figure>  <p>There were 15 terrorist attacks last year that had a higher death toll than last Fridays suicide bombings and gun attacks in Paris, the index showed.</p> <p>The deadliest attack of 2014 saw Isis storm a prison in the northern Iraqi city of Badush, <a href="http://www.theguardian.com/world/2014/aug/25/isis-ethnic-cleansing-shia-prisoners-iraq-mosul">killing about 670 people</a>.

Last year, terrorists killed 172% more private citizens than the year before. What were seeing is a change in tactics. Attacks on private citizens are more lethal, they create a lot more fear and mayhem in a society. This also has an economic impact, said Killelea.</p> <p>Terrorism cost the world $53bn last year in injuries, property damage and the loss of lifetime income for the people who were killed. But Killelea warned that this estimate is very, very conservative. Theres a lot of other flow-on effects of terrorism which were not able to really capture. </p>
