Nearly 200 women and children were injured in a bee attack on Sunday in Bihar's Arwal district, about 75 km from here, police said.
All of the injured were admitted to a local hospital.
"Honey bees attacked and injured 200 women and children in Arwal, when they had gathered under a banyan tree to perform a ritual relating to a local festival," a district police official said.
"Suddenly the bees came in a swarm and stung the people standing under the tree."
According to police officials, ostensibly the honey bee hive was disturbed because of the gathering.
