TASHKENT, Dec 14 (Reuters) - More than 100 people went on trial behind closed doors in Uzbekistan on Wednesday on charges of plotting or aiding an uprising in May, the latest in a series of cases to be sharply criticised by human rights groups. The Central Asian state's Supreme Court jailed 15 men last month over May's unrest in Andizhan, when witnesses say hundreds died when troops shot into crowds of protesters.

Human rights bodies condemned it as "a show trial" and the U.N. High Commissioner for Human Rights called it unfair. Uzbekistan's refusal to hold an independent inquiry into what happened has soured its relations with the West. The court said the 114 people on trial included 10 policemen, 19 army servicemen, five prison workers and two prison doctors. "As a result of their grave dereliction of duty, improper security of their facilities and negligent storage of arms and other criminal acts ... the terrorists seized a police station in Andizhan, an army unit and sprang hundreds of hardcore criminals from jail," it said in a statement. The Uzbek authorities say troops in Andizhan were attacked by Muslim extremists, who had trained abroad and were trying to establish an Islamic state in the fertile but impoverished Ferghana Valley. Witnesses then saw troops fire into a crowd that included many women and children. The authorities say 187 people -- mainly "terrorists" -- died.
