GENEVA (AP) — A U.N. panel has found serious shortcomings in the United States’ civil rights record, with experts citing Thursday a lack of adequate oversight and transparency in national security programs dealing with everything from electronic surveillance to targeted drone killings and secret detentions.

The report by the U.N. Human Rights Committee, a panel of 18 independent experts from different countries, found general improvement in some areas — such as the handling of rights of indigenous peoples and the Guantanamo Bay prisoners — since the last such review in 2006.
