KSRTC is unlikely to operate its city, moffusil and inter-district buses between 6 a.m. and 6 p.m. on Tuesday when the hartal has been called on the Mullaperiyar issue. Sources in the agency said that a few buses might ply with police escort.

Though buses have been kept ready for Sabarimala pilgrims at the Ernakulam bus stand, they will not operate if there are obstacles on the route.

Most buses would ply as usual from 6 p.m.
