Bangladesh's Supreme Court has commuted the death sentence for a leader of an Islamic political party to imprisonment until death for war crimes during the nation's 1971 independence war against Pakistan.

The original sentencing of Delwar Hossain Sayedee, a leader of the Jamaat-e-Islami party, sparked riots last year.

Chief Justice Muzammel Hossain of the Appellate Division of the Supreme Court said Sayedee would remain imprisoned "for the rest of his natural life."
