Maoists on Saturday blew up a culvert on an important road and put up posters opposing ‘Operation Green Hunt' in the Narayanpatna block of Koraput district in Orissa.

They also put up posters near Roxy of the K.Balanga block of Sundergarh district.

Deputy Inspector-General of Police (Southwestern range) Sanjiv Panda said the Maoists used landmines to damage a culvert on the crucial Narayanpatna-Laxmipur road near the Karki ghat. They also cut down trees to block the road near Jogi-Palur. At some places, the road was dug up and optical fibre cables were damaged disrupting telephone communication in most areas of the Narayanpatna block.

Mr. Panda said no one was injured as the blast took place early in the morning. Additional forces were sent to the area.

Following threat of landmines, the security forces were moving with caution.

The posters opposed ‘Operation Green Hunt' against the Maoists planned at Dantewada in Chhattisgarh, in Malkangiri and Koraput districts of Orissa and in parts of Andhra Pradesh.

Security had been tightened in the Narayanpatna block. During the past one year, several times the Maoists and the Chasi Mulia Adivasi Sangh blocked the area.
