A US document on atrocities committed in Liberia over the last three decades has been presented to the country's Truth and Reconciliation Commission.
Liberia suffered decades of unrest
Commissioners say the declassified papers - of the US government and intelligence agencies - will help substantiate allegations of brutality.
Liberia was torn apart by decades of unrest and civil war.
It was brought to an end in 2003 when former President Charles Taylor resigned as part of a peace agreement.
The commission was launched in 2006, after Ellen Johnson-Sirleaf came to power in presidential elections, so Liberians could speak up on crimes and suggest solutions on how to progress with them.
The Catholic Justice and Peace Commission of Liberia (JPC) handed over 4,000 declassified pages to the TRC.
"Today, the JPC is contributing these documents to the Truth and Reconciliation Commission as a means of healing our past and as an important step towards choosing a path of peace and dialogue," said Monsignor Andrew Karnley after handing over the documents.
The documents were obtained after a request made under the US Freedom of Information Act.
"The TRC has a mandate to investigate human rights in this country. With this document the TRC will be able to go forth with its work and give the Liberian people the true nature of our history," JPC head Augustine Toe told the BBC's Network Africa programme.
The TRC is now collating public statements to begin public hearings before the end of the year.
