The United Nations Human Rights Commissioner has criticised leaders in Nepal for not doing enough to tackle human rights violations.
Louise Arbour said political and military leaders could increasingly expect to be held to account.
The BBC correspondent in Kathmandu says Ms Arbour mainly directed her comments at the government side but said Maoists were also guilty of grave abuses.
More than 10,000 people have died in the nine-year Maoist insurgency.
Ms Arbour, sharing a platform with Prime Minister Sher Bahadur Deuba, said the conflict was having a corrosive and embittering effect on Nepalese society.
Ms Arbour is the first holder of her position to visit Nepal since the Maoist uprising began.
