Unfortunately, I'm not very well-read on national politics of various countries, so this isn't exactly my area to talk about.
Religious conflict has been incredibly common in world history, though, be they full-scale wars or massacres, genocides, etc. Terrorism is a pretty recent tactic, and like I said earlier, I assume that's because of how powerful communication has become- it uses the fact that information will spread as a weapon in itself.
What kind of examples are you looking to hear here, though? I know of many religiously-motivated massacres, both of whatever religion as well as between Muslims (a large amount of modern religious conflict is between different Muslims after all). Buddhists have committed massacres and fought in resistance movements, as an example.
I kind of wish I knew more African history just so I could give some good examples here, since that continent has been rife with all kinds of war and such over the last century or so, and unsurprisingly a large factor in that would be things like imperialism.
