Dimapur, October 25 (MExN): The names of Rengma and Pochury tribes, inadvertently omitted from a list of Naga tribes in a class-VI social science textbook earlier, are to be “added” and taught by all teachers. The SCERT in a notice issued by Director Vipralhou Kesiezie informed that this new arrangement would be employed till the new, correct ed textbook is made available, by December 10 this year.
