Condemning the deadly Maoist attack in Chhattisgarh, Amnesty International Thursday said the violence could put more civilians at risk.
"We unequivocally condemn the taking of hostages and murder of civilians in Chhattisgarh, which constitutes a serious human rights abuse," said Shashikumar Velath, Director of Programmes at Amnesty International India.
"The killing could further escalate violence in the state, putting more civilians - including local Adivasi communities - at risk," he added.
"Intentionally directed attacks against civilians, and violence to life and person go against fundamental principles of humanity."
In the May 25 attack, a Congress party convoy was ambushed by Maoists in a forested area of Chhattisgarh's Bastar region. At least 16 people were killed.
"Both the CPI-Maoist and state forces must refrain from committing any attacks that could lead to civilian casualties," Velath said.
