Video sharing site YouTube has banned terrorism training videos from being shown on their website.

From the AP (via Google News):

In addition to barring terror training videos, the new YouTube community guidelines include bans on videos that incite others to commit violent acts, videos on activities such as how to make bombs and footage of sniper attacks. Previously, it had policies in place against showing people “getting hurt, attacked or humiliated,” banning even clips OK for TV news shows.

YouTube has not identified specific videos on its site that led to the change, nor said exactly how it will choose those that are purged. YouTube does not deny that extremist groups could have used the site.

The Internet has become a powerful tool for terrorism recruitment. What was once conducted at secret training camps in Afghanistan is now available to anyone, anywhere because of the Web. Chat rooms are potent recruitment tools, but counterterrorism officials have found terrorist-sponsored videos are also key parts of al-Qaida’s propaganda machine.
