Worst terrorist attacks

Terrorism has increased dramatically over the last decade. In 2013 alone there was a 61% increase in the number of people killed in terrorist attacks. In the same year, there was a total of 9,814 terrorist attacks which killed 17,958 people.

While terrorism is increasing, the types of attacks, weapons used and targets are also changing. If we look at where the majority of terrorism is happening, we can see that it is very concentrated. In 2013, 82% of all those who were killed in terrorist attacks were in just 5 countries.

In analysing these five countries and others that suffer a high impact of terrorism, we can start to understand the sort of environments where terrorism can flourish. While drivers of terrorism are often complex,  countries with higher levels of terrorism were found to have three common traits: greater hostilities between different ethnic, religious and linguistic groups, a high level of state sponsored violence, and high levels of crime and violence.

The map below shows the worst terrorist attacks (in terms of the number of people killed) since 2000 in red, and the worst attacks in 2013 in blue. 

In 2013, the five worst terrorist attacks, in terms of the number of people killed, were:

Nigeria, 17th of September members of Boko Haram set up illegal checkpoints and killed 142 civilians.

Syria, on the 22nd of July, assailants attacked soldiers and civilians in the town of Khan Al-Assal, killing 123 people.

Pakistan, on the 10th of January, suicide bombers detonated inside a snooker all in Quetta killed 107 people and wounding 169. Lashkar-E-Jhangvi were responsible.
