GENEVA (AP) — U.N. human rights experts are calling on the United Arab Emirates to release five Libyans, including three with Canadian or U.S. dual citizenship, who were allegedly tortured while in detention over the last year and a half.

U.N. special rapporteur on the right to health, Dainius Puras, says most of the detainees don't have adequate access to medical care and face health problems including loss of sight and hearing due to the alleged torture.

The U.N. on Monday identified the five as Adel Rajab Beleid Nasef; Moad Mohamed Al Hashmi; Salim Alaradi, who also has Canadian citizenship; and father and son Kamal Ahmed Al Darrat and Mohamed Kamal Al Darrat, who are also U.S. nationals.

The experts said they found a reply from Emirati authorities about their cases "unpersuasive."
