Islamic terrorism is a form of terrorism by those whose motivations are rooted in extremist interpretations of Islam.  Over 25% of terror-related attacks of violence in 2007 were caused by those self-identifying as "Islamic", according to the United States Government. Islamic terrorists use verses from the Qur'an to justify their actions (see below). Islamic terrorism is imprinted strongly anti-American and anti-Zionist.
The Roots of Terror
According to the National Counterterrorism Center, the Islamic State of Iraq (aka al-Qa’ida in Iraq), more than any other subnational group, claimed they conducted attacks with the highest casualty totals. 
Qur'an Verses that endorse terrorism
- [2:191]: "And kill them wherever you overtake them and expel them from wherever they have expelled you, and fitnah is worse than killing."
- [8:55]: "Indeed, the worst of living creatures in the sight of Allah are those who have disbelieved, and they will not [ever] believe "
- [47:4]: "So when you meet those who disbelieve [in battle], strike [their] necks until, when you have inflicted slaughter upon them, then secure their bonds, and either [confer] favor afterwards or ransom [them] until the war lays down its burdens. That [is the command]. And if Allah had willed, He could have taken vengeance upon them [Himself], but [He ordered armed struggle] to test some of you by means of others. And those who are killed in the cause of Allah - never will He waste their deeds."
The best known islamic terror organization is Al-Qaeda, or "the base". It was founded by Osama bin Laden and Ayman al-Zawahiri in Afghanistan during the 1980's. There are, however, numerous other terror groups including Islamic Jihad, Hamas and the Shia Hezbollah. The Islamic State is seen as the most brutal organization, even al-Qaeda distances from it.
