Noted writer and ULFA peace talk facilitator Indira Goswami on Wednesday threatened to pull out of the exercise to bring the militants to the negotiating table.
"Lots of people have died due to violence and the peace effort seems to be lost...If there is no headway I'll have to consider withdrawing from the process," Goswami said in Guwahati.
Urging ULFA to send a letter to the Centre explaining its reasons for taking up arms and a possible solution, the Jnanpith award winner said the government should also respond positively.
"Otherwise there is no end to the conflict and it will end in violence and cause harm to the society," she said.
Goswami had earlier urged the Centre to consider amendment to the Constitution to discuss the sovereignty demand of the ULFA.
"Several amendments have been made to the Constitution from time to time...So I do not see why such an exercise cannot be done in case of the ULFA's demand," she said.
The peace process has been derailed with the ULFA's insistence on including its demand for sovereignty in the talks and the Centre rejecting it.
