Hyderabad: The Naxalites of the outlawed People's War Group (PWG) blew up a railway engine in Nizamabad district and a telephone exchange in Guntur district on December 14 night, police said.

Both the incidents were of retaliatory nature in protest against the arrest and encounter deaths of fellow ultras in November in Guntur district and elsewhere.

At about 01:30 hours (IST) on December 15, armed Naxalites boarded a slow-moving diesel engine in Sadashivnagar Mandal limits on Nizamabad-Secunderabad track and asked the driver and helper to get down before blowing up the engine.

The railway traffic on the Nizamabad and Secunderabad section of SCR has been affected and the railway authorities had pressed workers in removing the damaged engine.

In another incident on December 14 night in Guntur district, Naxalites blasted a 200- line telephone exchange building in protest against the arrest of Naxal activist Kottaiah last month, police added.
