Maoists burnt 32 vehicles in Bihar's Gaya district to enforce a two-day shutdown beginning Monday to protest the killing of a woman leader of the rebel group, police said.
They also blew up a mobile phone tower in Panapur area in Saran district, about 100 km from here.
"A group of Maoist guerrillas forcibly stopped vehicles on the busy Grand Trunk road in Gaya and torched them post midnight on Sunday to create panic," Gaya Senior Superintendent of Police Manu Maharaj said.
Around two dozen trucks were among the vehicles set on fire. The Maoists are also protesting security forces operation against them, police said.
The drivers of the burnt vehicles told police officials that Maoist guerrillas asked them to get away from the vehicles before setting them afire.
Taking serious note of the attack, police headquarters in Patna directed the district police to intensify combing operations against Maoists.
