The CPI(M) and CPI also asked their party units to urgently collect funds and materials to help those affected.
Stressing the urgency of immediate rescue and evacuation operations by the Centre, the state government and their agencies, CPI(M) said the Uttarakhand government must also probe the role that "the indiscriminate tunnelling of the hills by power projects and the huge dumps of silt which were never cleared, had to play in this terrible tragedy."
"The horror and immense tragedy of the loss of human lives and unprecedented destruction of homes and livelihoods in the Kedarnath, Chamoli and other regions of Uttarakhand is still unfolding," it said while expressing deep condolences to the families of those who have lost their lives.
The CPI Central Secretariat also termed the devastation as "man-made" and said all norms were flouted in allowing construction of a large number of hydropower projects in Uttarakhand by both Congress and BJP regimes.
