That's because MSM is too scared to call it what it is exactly i.e. Islamic terrorist. By default, MSM assumes the West and the Christians are to be blamed always and for everything. Everyone else in the world is just nice, innocent human being. Incident like this really don't fit their narrative. That's for the US and western media. As far as the lack of coverage in Nepali media, they don't really do any kind of reporting of their own. They just regurgitate what's already put out there by big media house worldwide. As far as Nepali public showing lack of interest on this incident....well, their sense of global citizenship is too weak to empathize with the suffering of some people from some other country in the globe. Yes, they will share and re-post what's trending (Syria and shit) but that is IT, no initiative from their own. Last but not the least, Sri Lanka govt was to be blamed too by banning social media in the early hours of the incident, should have shown the true color of Islam to the world while the news was still hot.
