Iraq has executed 21 people convicted of terror-related charges, including three women, on the same day, a justice ministry spokesman said on Tuesday, Aug 28, according to AFP.

"The justice ministry carried out 21 executions against those condemned of terrorist charges, including three women terrorists," Haidar al-Saadi said in a text message. He did not give any further details.

A justice ministry official said the executions were carried out on Monday morning.

Amnesty International in June condemned the "alarming" increase in executions in Iraq, which had at that point put at least 70 people to death this year, more than all of 2011.

Iraq has carried out several mass executions in 2012, including one in which 14 people were put to death on February 7, and another in which 17 were executed on January 31.

UN High Commissioner for Human Rights Navi Pillay expressed shock earlier this year at the number of executions, criticizing the lack of transparency in court proceedings and calling for an immediate suspension of the death penalty.
