New satellite images from the Central African Republic show the "shocking" aftermath of recent violence, according to Amnesty International.
The country has been in crisis since a rebel takeover in March.
The human rights group says the images show significant fire damage to 485 homes in the northern town of Bouca.
Some of the thousands of people who have fled the violence can be seen massing in nearby Bossangoa, Amnesty says.
It is not publishing those images out of concern for the safety of the displaced people, it says.
"These new images offer a glimpse of physical scarring to homes and civic life visible from space, but the true scale of the human impact of the crisis cannot be captured by satellite," said Aster van Kregten, from Amnesty International.
The Seleka coalition of armed rebels ousted President Francois Bozize earlier this year.
Since then the rebels have committed human rights violations on an "unprecedented scale," according to Amnesty.
Meanwhile the United Nations' World Food Programme says that 1.1 million people in the CAR risk going hungry because of the conflict.
The agency fears that food from the most recent harvest could run out in January or February 2014.
The WFP's representative in CAR called upon the armed groups in the country to respect the rights of civilians, and allow WFP staff access to those in need.
"Immediate action must be taken to end violence in the country to allow hundreds of thousands of displaced persons to return to their homes and farms," said Housainou Taal.
