New Delhi, Jun 28 () Naga militant leader

Isak Chishi Swu

, who led a bloody insurgency in the Northeast for over three decades, died here today following multi-organ failure. The 87-year-old Chairman of

Nationalist Socialist Council of Nagaland

(

NSCN-IM

) was undergoing treatment for almost a year at a private hospital in South Delhi where he breathed his last around noon,

Nagaland

government spokesperson

Kuolie Mere

said. Swu, who belonged to the Sumi tribe, hailed from the

Zunheboto

district of Nagaland and his body will be taken to his native place tomorrow for last rites. Swu along with NSCN-IM general secretary

Thuingaleng Muivah

formed the group in 1980 opposing the

Shillong

Accord signed by the then

Naga National Council

(NNC) with the central government for bringing peace in Nagaland. Over the years, NSCN-IM has been accused of indulging in killings, extortion and other subversive activities. Its persistent demand for separation from the country, led to military clamp down on the group. In 1997, NSCN-IM entered into a truce with the central government for peace and since then has been continuing dialogue with centre's emissaries. In August last year, the NSCN-IM signed a framework agreement with the government which Prime Minister Narendra Modi described as a "historic" step to usher in peace in the state. The pact was signed in the presence of the Prime Minister, Home Minister Rajnath Singh and National Security Adviser Ajit Doval by

Muivah

and government's interlocutor R N Ravi at the PM's residence here. The signing of the pact came after over 80 rounds of negotiations that spanned 16 years with first breakthrough in 1997 when the ceasefire agreement was sealed. Swu joined the Naga National Council (NNC) in the 1950s and served it in different capacities till its split in 1980. ACB VMN VMN
