There are several terrorist groups who claim to be fighting because of religion - although whether you believe that is really their only motivation is up to you to decide. Some known terrorist groups who claim to be fighting based on religion include:
Hamas in the Gaza strip Hezbollah in Lebanon
They claim to be Muslim, but just like christianity there are many sects of the religion and they are the most extreme sect of the religion
First of all, the fighting in Iraq has been occurring against terrorist insurgencies. Since terrorist insurgencies are not a solid military group, they are scattered throughout their country, making direct combat with them very spread out.
al-Shabaab, a militant islamist group has gained control over much of somalia and is 'fighting' the Somali government.
