Guwahati, July 11: One of the most powerful insurgent groups in India said on Monday it would extend a seven-year-old ceasefire with New Delhi that ends on July 31 in order to push for a peaceful solution to a decades-old revolt.

The NSCN I-M, fighting for the independence of three million Naga tribesmen in the remote northeast, said it would see how the government responded to its decision, taken after talks between rebel leaders and New Delhi failed to make progress this year.

�We are committed to extend the ceasefire by another year,� RH Raisingh, a senior NSCN (I-M) leader, told Reuters by telephone from Nagaland.

�The progress of the talks was not to our satisfaction but we are optimistic about a finding a solution�.

Raisingh said specific dialogue on extending the truce would be held outside India but did not say where it would be held.
