Security has been tightened across the  Dhaka Central Jail where he is currently lodged.

"A hangman has been seen entering the Dhaka Central Jail where death convict war criminal Motiur Rahman Nizami is being kept. Security has been tightened around the jail," The Daily Star newspaper reported.

Meanwhile, country's Home minister Asaduzzaman Khan Kamal said Nizami could  be hanged anytime in case he did not plead for his life.

"Wait and see,” Kamal was quoted as saying by Prothom Alo when he was asked about the day of Nizami's execution.

The Bangladesh Supreme Court on Thursday rejected the final plea to review his death sentence handed to fundamentalist Jamaat-e-Islami Motiur Rahman Nizami.

International Crimes Tribunal-1 had earlier handed a death sentence to him on October 29, 2014 over war crimes committed  during the 1971 Liberation War with Pakistan.

The judgement was pronounced by four-member Appellate Division bench headed by Chief Justice Surendra Kumar Sinha.
