DHAKA: Bangladesh's Supreme Court Wednesday upheld the death sentence of Jamaat-i-Islami Emir Motiur Rahman Nizami for alleged crimes in 971.

The court led by chief justice S.K. Sinha dismissed an appeal by Niazmi, who was sentenced to be hanged allegedly for murder, orchestrating the killing of top intellectuals and other crimes as the head of a militia.

"The court upheld the death sentence in three out of four charges," prosecutor Tureen Afroz told reporters.

Nizami, 72, Jamaat's leader since 2000 and a minister in a former Islamist-allied government of 2001-2006, now faces the gallows within months unless his case is reviewed by the same court or he is granted clemency by the president.

Three senior Jamaat officials and a key leader of the main opposition have been executed since December 2013, despite global outcries over the shortcomings of their trials by a controversial war crime tribunal.
