Police in Nepal's capital, Kathmandu, have used batons to break up a protest by supporters of former Prime Minister Sher Bahadur Deuba, who appeared before an anti-graft body. Witnesses say protesters retaliated by throwing stones and bricks at police. At least 15 demonstrators were injured in Sunday's skirmishes. Mr. Deuba, who was dismissed after King Gyanendra seized absolute power in February, is being tried by Nepal's anti-graft commission on embezzlement charges. Last month, the panel acquitted him of illegally distributing state money to party supporters. But he still faces a separate charge of embezzling millions of dollars in a drinking water project. Mr. Deuba has denied the accusations. He was arrested in April after he refused to testify, saying the commission is unconstitutional.
