Authorities in the United Arab Emirates have tortured a Libyan-Canadian man who has been held for a year on suspicion of having links to the Muslim Brotherhood, Amnesty International said Friday. "The unlawful treatment of Salim al-Aradi demonstrates the extreme tactics the UAE authorities are resorting to in the name of protecting national security," said Amnesty's Middle East and **rth Africa deputy director Said Boumedouha. The group said that Aradi was among 10 Libyan businessmen arrested in the UAE, four of whom were released in December and deported to Turkey.
