The Supreme Court in the Central Asian nation of Kyrgyzstan has begun reviewing the case of an ethnic Uzbek journalist and activist serving a life sentence after being convicted of stirring up ethnic hatred.

International rights groups consider Azimzhan Askarov a prisoner of conscience and the U.N. Human Rights Committee has recently urged Kyrgyzstan to release him.

Kyrgyzstan's Supreme Court opened the hearings on Monday.

Charges against Askarov relate to the 2010 massacre in the south of Kyrgyzstan when more than 450 people, mostly ethnic Uzbeks, were killed and tens or even hundreds of thousands were displaced by the unrest. The majority of those convicted for taking part in the deadly clashes are ethnic Uzbeks.
