WASHINGTON (AP) — A United Nations group is calling on the Cuban government to release an American who has been held in the country for more than three years, saying his detention is arbitrary.

A 12-page report by the U.N. Working Group on Arbitrary Detention was released Tuesday by a lawyer for the American, Alan Gross. The report is dated November 23 and had been earlier released to the Cuban government.

Cuba blasted the report’s conclusion in early December, saying that the U.S. government had put pressure on the UN group and arguing Gross had been fairly tried. But Cuban officials did not release the report itself.
