Baghdad, Nov 1, (RHC-Xinhua) -- A total of 1,273 Iraqis were killed and 2,010 others were injured in terrorist attacks and violence in October in Iraq, according to a statement issued on Saturday by the UN Assistance Mission for Iraq (UNAMI).

The statement said that 856 civilians, including 139 civilian policemen, and 417 Iraqi security forces personnel were killed, while 1,490 civilians including 172 civilian policemen were wounded. An additional 520 security members were wounded in terrorist and violent acts during 31 days of the month.

The UNAMI excluded the casualties in Anbar province where fierce clashes flared up after Iraqi police dismantled an anti- government protest site outside Ramadi in late December last year.

UN envoy and UNAMI chief Nickolay Mladenov voiced deep outrage about worsening violence that targeted all Iraqi factions by the Islamic State in Iraq and Levant (ISIL), which later named the Islamic State group (IS), including those whose bodies were discovered in mass graves in western Iraq.

"Justice and accountability for those responsible for these mass executions, killings, disappearances and displacement must be ensured," he said.

The security situation in the country has drastically deteriorated since June 10, when bloody clashes broke out between Iraqi security forces and hundreds of Islamists militants from an armed group called the Islamic State (IS).
