First of all it is clear that they are targeting the most important places of India and South India is rising nicely and most of the population is well educated. Country\'s economy is growing well with the help of South India, hence it is their target.Further in Delhi the security is quite tight, though they are targeting off and on. Secondly, it is senseless to say that jihadi activities have increased after babri demolition, this version is nothing but to divert the issue. Further, most of the terrorist groups seem to be supported by some of the political groups, hence they are getting prosperity, which may be looked into. JK Sharma
