It is never title, or even in the first few paragraphs. It sometimes isn't mentioned at all. But, where there is terrorism, you will almost always find "radical" Islam, or Islamic extremists. Here it is in the very last sentence of the article:
All of India's major cities were reportedly on high alert following the attacks, which came hours after a series of grenade attacks by Islamic extremists killed eight people in the main city of India's part of Kashmir.
Of course, it isn't mentioned that the train bombing was caused by "Islamic extremists". We wouldn't want to jump to hasty conclusions.
