The state government has also decided to write to the Centre demanding the repeal of the Armed Forces (Special Powers) Act, they said.
Six tribes under Eastern Nagaland People's Organisation and a few other tribes decided to refrain from participating in the cultural programmes.
Demand for repeal of the act found echoes in the nation's Parliament with National People's Party (NPP) MP Agatha Sangma, a former Minister in the United Progressive Alliance government, terming the act as 'the elephant in the room which (needs to) be addressed' and seeking the 'draconian' Act be repealed.
The first firing which killed six civilians, occurred when army personnel mistook coal mine workers returning home in a pick-up van singing songs on Saturday evening, to be insurgents belonging to the Yung Aung faction of the banned outfit National Socialist Council of Nagaland-Khaplang (NSCN-K), about whose movements they had been tipped-off.
