Amnesty International says human rights in Bangladesh and Sri Lanka have deteriorated in recent years.
In a report, the group says hundreds of human rights workers in Bangladesh are being threatened, attacked, charged without cause and arrested or tortured. It says at least eight have been killed since 2000.
Amnesty says the victims are people who criticize the authorities or speak about human rights, such as journalists and lawyers.
In a separate report on Sri Lanka, Amnesty says there have been a large number of political killings since security forces and Tamil Tiger rebels resumed fighting last year. Many people, it says, have been killed or tortured while in police custody.
Amnesty's India director, Mukul Sharma blames both sides for the rise in human rights abuses.
Human Rights Watch also has released a report on Sri Lanka, accusing the government of failing to stop the recruitment of child soldiers by a breakaway faction of Tamil Tiger rebels.
