A small portion of railway lines were damaged when a landmine planted by Maoists went off in the Harichandanpur area of Keonjhar district on Wednesday.
None was hurt in the incident on the Jakhpura-Bansapani railway line between Sagadpata and Tangiriapal yesterday, the sources said. Since only a small portion of the track was damaged, train services on the route remained unaffected. A detonator and some wire were recovered from the spot.
