Kolkata, Oct 3 (Inditop.com) Suspected Maoist guerrillas triggered a landmine blast on the railway tracks in Purulia district of West Bengal early Saturday, police said.

The explosive went off on the railway tracks near Urma station after midnight, affecting train movement in the Adra-Chandil division.

The leftist ultras have called for a nationwide strike Saturday to protest the recent arrests of their leaders Kobad Ghandy and Chhatradhar Mahato and to demand their release.

“We’re yet to ascertain the type of explosive the Maoist ultras used in the blast. We’ve sent our expert team to the spot to examine everything.

“The incident affected train services on the Adra-Chandil division for a while, but now it has been resumed,” Inspector General of Police (Law and Order) Surajit Kar Purokayastha told Inditop.
