Iran on December 20 hanged a woman convicted of murdering her husband, whom she married while still a child, defying an international campaign for clemency, rights groups said. Samira Sabzian, who had been in prison for the past decade, was executed at dawn in Ghezel Hesar prison in the Tehran satellite city of Karaj, the Norway-based Iran Human Rights group said. Her execution comes as concern grows over the numbers of people this year executed by Iran, where hundreds of people have been hanged mainly on drug and murder charges, including more than a dozen women.
