The United Nationsinfo-icon said Monday that terrorism and other acts of violence in Iraqinfo-icon killed at least 6,878 civilians and wounded another 12,388 last year.

But the casualty figures may actually be higher because they do not include civilians who were killed or injured in Iraq's western Anbar province during the months of May, July, August and December.

The numbers "have to be considered as the absolute minimum," according to the U.N. Assistance Mission for Iraq (UNAMI).

The U.N. said civilian casualty figures for December are lower compared to previous months, despite noticing an increase in terrorist bombings toward the end of the month that targeted civilians.

Violence had claimed the lives of at least 7,515 civilians in Iraq in 2015, according UNAMI figures.

Over the past months, Iraq has been rocked by a wave of bomb attacks, mostly claimed by the Takfiri Daesh terrorist group.

The militants have recently increased their acts of violence across the country in revenge for the blows they have been suffering at the hands of Iraqi forces, particularly in the northern city of Mosulinfo-icon.

"This is, no doubt, an attempt by Daesh to divert attention from their losses in Mosul and, unfortunately, it is the innocent civilians who are paying the price," said Jan Kubis, the special representative of UN Secretary General in Iraq and UNAMI head.

Daesh began its campaign of terror in northern and western Iraq in 2014.
