The announcement came hours after police prevented opposition leader Khaleda Zia from leaving her house here to address a banned mass march.
"We will protest (against the government's move) taking position on the roads, railways and waterways like Mahatma Gandhi's Satyagraha," BNP's vice-president Hafizuddin Ahmed told a press conference at the National Press Club here.
"This is not a new idea," Ahmed said referring to Gandhi who had introduced the Satyagraha or nonviolent resistance to fight colonial British regime in India.
BNP's 'Dhaka March' will continue tomorrow, he added. "Opposition Leader Khaleda Zia will lead the demonstration."
