There has been a sharp increase in the number of militant groups using the Internet for their activities. In 1998, about half of the 30 militant groups that were labelled terrorist organizations by the US maintained websites. By 2000, almost all terrorist groups had established their presence on the web. According to Gabriel Weimann, senior fellow at the Washington-based United States Institute for Peace (USIP) and professor at the Haifa University in Israel, the number of terrorist-run websites has increased by 571% over the past seven years.

The Internet has become the terrorists’ preferred choice of communication for the same reasons it is popular among people in general: it is quick, inexpensive and easily accessible. What makes it particularly attractive to terrorists is that it gives access to huge audiences spread across the world, provides anonymity and is hard to police or regulate.

Not only have the number of terrorist websites increased, but also the uses to which terrorists put the Internet have diversified. Its use as a propaganda tool is perhaps the most overt. Terrorist websites typically outline the nature of the organization’s cause and justifications for the use of violence. The Liberation Tigers of Tamil Eelam (LTTE) website, for instance, carries accounts of the LTTE’s “freedom struggle”, the legality of its demand for an independent Tamil Eelam and the legitimacy of its armed struggle. The website carries interviews given by LTTE leader Velupillai Prabakaran and his speech on “Heroes Day”. It also carries press releases that provide the media with its take on events in Sri Lanka.

But use of the Internet as a propaganda tool is just the tip of the iceberg. Terrorists are using the Internet as a weapon in psychological warfare, to raise funds, recruit, incite violence and provide training. They also use it to plan, network and coordinate attacks. Thomas Hegghammer, who researches Islamist websites at the Norwegian Defense Research Establishment, says that “in a sense, [the Internet has] replaced Afghanistan as a meeting place”.
