The United Naga Council (UNC) alleged that "communal forces in Imphal Valley" were working against them but did not identify them.
Demanding "an alternative arrangement" for Nagas, the UNC said in a statement that, "Nagas have consistently maintained that we are not communal but the Nagas and tribes cannot live with dignity and honour under the communal government of Manipur."
Officials said all efforts would be made to ply transport services during the bandh.
While air services will not be affected, vehicle movement will be hit as they have to pass through a major portion of Naga-settled areas.
