I may have misread the reports (now up to 207 dead and over 450 injured) but the attacks in Sri Lanka were on churches and hotels.

Clearly Christians were one target (presumably to create inter-faith conflict and the type of international headlines generated in the last few hours - much like the thread header) but so were Sri Lankan workers (and police), holidaymakers and foreign tourists.

A wider range of victims and probably more complex motives than you suggest. A barbaric act.
