The DYFI will organise a rail roko agitation in the State on Tuesday to protest against the Centre's polices which allegedly increased unemployment. The State secretariat of the DYFI said here on Saturday that the organisation would take out marches to railway stations in all the major centres of the State and block trains for half an hour from 11 a.m. In Wayanad and Idukki districts, the workers of the organisation would block the National Highway. — Special Correspondent
