Protesting against the death of two young Dalit children who were burnt alive while they were asleep, residents of a village in Haryana blocked a highway near Delhi today and demanded that all the accused be arrested at the earliest. The children, aged two-and-a-half years and 11 months, died after their house in Sonped on the outskirts of Delhi was set on fire on Monday, allegedly by members of an upper caste community.
