Bangladesh has executed the Islamist leader Abdul Kader Mullah, convicted of atrocities in the 1971 war of independence with Pakistan.
He is the first person convicted by Bangladesh's International Crimes Tribunal (ICT) to be executed.
The ICT was set up in 2010 to investigate abuses committed during the 1971 conflict, in which some estimate three million people were killed.
Mullah was a senior leader of the Jamaat-e-Islami party.
His trial earlier in the year sparked protests from Jamaat supporters.
Mullah had been scheduled to be hanged on Tuesday, before gaining a reprieve pending a last-minute appeal.
The Bangladeshi Supreme Court dismissed the appeal earlier on Thursday.
The 65-year-old was hanged inside Dhaka central jail at 22:01 local time (16:01 GMT).
Security has been tightened in the capital.
Those being tried by the ICT are accused of collaborating with Pakistani forces who attempted to stop East Pakistan, as Bangladesh was then, from becoming an independent country.
However, human rights groups have claimed that the tribunal falls short of international standard
