"The NSF, or for that matter the Nagas, have nothing to say over the demand for autonomous or separate state by the Karbi people.
"However, imposing a 1,000-hour bandh on National Highway, thereby cutting off the route which is the only life-line for the people of Nagaland, is a matter of great concern," said NSF vice-president Joseph Ngouri and general secretary Esther Rhakho in a release here today.
The NSF also urged the Union Home Ministry to take necessary measures for the safety people plying through the Karbi Anglong district of Assam.
