Twelve persons including eight of Nepali origin had been killed when NDFB militants opened fire in Bhimaji village.
Those killed include Danu Mani Bahadur Pradhan, Ganesh Chhetri, Chandra Chhetri, Uma Devi, Kuleshwar Pradhan, Ranju Pradhan, Bhuwan Newar and Man Bahadur Chhetri.

Associations of Nepali speaking organisations had been agitating demanding at least IRs 1,000,000 to the families of the deceased.
