Shillong, Aug 3 (IANS): The details of the historic peace accord signed on Monday between the government and the National Socialist Council of Nagaland-IM will be made public soon, a top official from the Prime Minister's Office said.

"The finer details of the text of the agreement will come out shortly," the PMO official told IANS on condition of anonymity.

He said the peace accord would bring a new dawn of peace and development to the region in general and Nagaland in particular.

Nagaland Chief Minister T.R. Zeliang congratulated Prime Minister Narendra Modi over signing the peace accord.

"In principle, we congratulate the prime minister for signing the peace accord, but we cannot comment anything on it as we do not know the contents of the agreement," Zeliang told IANS.

Modi, who had a telephonic talk with Zeliang after signing of the peace accord, said the deal was an inspiration in "our troubled world" and noted that the Naga problem was a legacy of the British which took a long time to resolve as "we did not understand each other".

Since 1997, the two sides have held at least 50 rounds of peace talks aimed at ending one of South Asia's longest running insurgencies that has claimed an estimated 25,000 lives since India attained independence in 1947.
