Goa Chief Minister Pramod Sawant and his Delhi counterpart Arvind Kejriwal were involved in a war of words on Twitter on Thursday over the South Western Railway's track-doubling project in and around Mollem village in South Goa.

Soon after Aam Aadmi Party supremo Kejriwal urged Sawant to "listen to the voice of people of Goa" and stop the central government from "foisting" the project on Goa, Sawant taunted Kejriwal by suggesting that he was an "expert in creating rifts" between the Centre and states.
