The crucial meet between NSCN-IM leaders and the Government of India representatives ended on an inconclusive note in New Delhi, said sources.
The sources added that they will sit again for another round of talks within few days.
The meeting which was touted to be the last round of formal talks between the two sides began around 2.30 pm and lasted till 6 pm.
A 15-member NSCN-IM delegation led by general secretary Thuingaleng Muivah attended the meet.
As per highly informed sources, the NSCN-IM leaders have got into a huddle after the meet. This meet had assumed significance in the wake of the rapid developments surrounding the Naga Peace talks in the last couple of weeks.
While the NSCN-IM is adamant on its stand on the separate flag and constitution issue, the government of India had ruled out any discussion on these two.
