GAUHATI, India: A group of tribespeople in northeastern India are enforcing a general strike to protest the killing by police of two of its members.

T. Moses Kamba, a spokesman for the Naga tribespeople’s United Naga Council, says Saturday’s clash with police during a march by hundreds of council supporters left 13 other tribespeople injured.

The council is demanding a speedy conclusion of peace talks to end one of the longest-running insurgencies in the region.

The council sent a memorandum to Indian Prime Minister Narendra Modi on Sunday accusing authorities of violating a 1997 cease-fire accord by militarizing Naga areas in the northeast.

The Indian government and the National Socialist Council of Nagaland, led by Thuingaleng Muivah, have been holding talks since 1997, but have failed to find a solution so far.
