A crucial round of talks to find a lasting solution to the seven-decade-old Naga insurgency problem was held on Thursday but the dialogue remained inconclusive, sources said.
A team of the NSCN-IM, led by its general secretary Thuingaleng Muivah, and Centre's interlocutor and Nagaland Governor R N Ravi discussed various demands raised by the group, they said.
However, the dialogue with the National Socialist Council of Nagaland-IM remained inconclusive and may resume after a few days, the sources said.
There is a possibility of Ravi holding the talks with other Naga insurgent groups like NSCN (Neopao Konyak/Kitovi), NSCN (Reformation) and NSCN (K-Khango) on Friday.
Sources said the issue of a separate flag and constitution for the Nagas has become the main contention between the two sides with the NSCN-IM strongly pressing for it.
