Suspected Maoists blew up portion of a bridge over a canal in Bihar's Aurangabad district on Monday apparently to obstruct movement of police vehicles.
The Naxalites blew up with dynamites a part of the bridge on Deo-Baluganj Road near Berhni village in the wee hours, Superintendent of Police Ganesh Kumar told PTI.
The SP said though small vehicles could still negotiate the bridge, no big vehicle can now pass over it.
Even though no ultra left organisation had claimed responsibility, it was suspected to be the handiwork of the CPI(Maoist), he said.
The bridge was blown up apparently to prevent police vans and armoured vehicles from reaching Maoist strongholds of Baluganj and Ketaki as the stretch became non-motorable, he said.
