Lucknow: One person was killed and another critically injured as two communities clashed on Republic Day in Kasganj district of Uttar Pradesh on Friday, police said.

The incident took place when a "Tiranga Yatra" in the form of a bike rally was taken out by the Akhil Bharatiya Vidyarthi Parishad (ABVP) and some other Hindu organisations in the town.
