United Nations ? A U.N. investigation has found that the United States committed acts amounting to torture at Guantanamo Bay, including force-feeding detainees and subjecting them to prolonged solitary confinement, according to a draft report obtained Monday.

U.S. officials rejected the draft report, saying the experts who wrote it made many errors and treated statements from detainees’ lawyers as fact. The United States had invited the experts to Guantanamo but would not let them interview detainees, so they refused to go.

The report recommended the United States close Guantanamo Bay and revoke all special interrogation techniques authorized by the Defense Department. Its experts accused the United States of violating the detainees’ rights to a fair trial, freedom of religion and health.

Many of the allegations have been made before, but the document is the first such accounting from an inquiry launched by the U.N. Commission on Human Rights.

The draft was delivered to the United States on Jan. 16, and was first disclosed Sunday by the Los Angeles Times. A final version was expected to be released later in the week.

State Department spokesman Sean McCormack said the United States would not address many of the claims until the final report is released, but defended the U.S. practices generally.
