Ranchi, April 23 (Inditop) Maoist guerrillas Thursday unleashed a wave of violence in Jharkhand as voting began for eight of the 14 Lok Sabha seats, triggering landmine blasts near polling booths, attacking a paramilitary camp and blowing up a railway station.

Several people were injured in the attacks that spread out in many parts of the state and included intermittent gunbattles that continued for hours in the forested areas of Jamshedpur and Giridih.

Giving details of the violence, police said three people, including two officials going to polling booths for the second and last phase of the parliamentary elections, were injured in a landmine blast triggered by Maoist rebels in Kalamajo village of Giridih district.

Police said the Maoist rebels, who have called for a poll boycott, also triggered an explosion on the road between Giridih and Dumri and cut trees to block it early Thursday.

Dramatic scenes were also played out in nearby Ghatshila forest of Jamshedpur district where police used helicopters against the rebels who were exchanging gunfire with security personnel.
