Armed Maoists blasted two schools at a village in Bihar's Kaimur district on Monday, police said.
Over 200 ultras raided the Duddha village and confined the villagers within their houses in the wee hours of Monday before blasting a government and a church school with dynamites.
Both the schools were badly damaged after the blast, the police said adding that no injuries or casualties were reported in the attack.
After carrying out their operation, the Maoists later vanished into the forests.
Patrolling by security forces was intensified as tension ran high in the area even as raids are on to apprehend the ultras, the police said.
