Human Rights Watch is asking authorities in Uzbekistan to provide immediate medical care to a jailed opposition leader.
The New York-based organization said Tuesday Sanjar Umarov, the leader of the opposition Sunshine Coalition, was arrested last month on embezzlement charges.
Human Rights Watch says when his attorney went to see him days later in a Tashkent detention facility, Mr. Umarov was incoherent.
The organization says the incident is the latest in what it calls the Uzbek government's "ruthless crackdown on dissent."
They are urging President Islam Karimov's government to provide Mr. Umarov with medical care and release him pending a review of the charges.
