"The ministry executed 11 people today, after they were convicted of terrorism charges," it said in a statement. "The total of those executed this week is now 37, all of them Iraqis."
Executions in Iraq are typically carried out by hanging, and large numbers are typically announced at once by the justice ministry. On Sunday, 26 people were executed.
Iraq has faced widespread criticism from diplomats, analysts and human rights groups who say that due to a problematic justice system, those being executed are not necessarily guilty of the crimes for which they were sentenced to die.
The country executed at least 169 people last year, according to an AFP tally based on statements from the justice ministry and reports from officials.

It was the highest figure since the US-led invasion of 2003, and placed it third in the world for the number of executions after only China and Iran.
The rise in executions in 2013 and the early part of this year comes as Iraq grapples with its worst prolonged period of violence since it emerged from brutal sectarian fighting that peaked in 2006-2007 and left tens of thousands dead.
