The figures, released Monday, indicate 227 Iraqi security forces were killed and 300 injured during the month.
"The United Nations deplores the continuing loss of civilian life resulting from acts of terrorism and armed conflict," said Francesco Motta, the chief human rights officer of UNAMI and representative of the high commissioner for human rights in Iraq. "Of equal concern is the toll on members of Iraq's security forces who are called upon on a daily basis to combat terrorism and violence and to protect the lives of civilians and civilian infrastructure."
The country has suffered attacks perpetrated by a number of terrorist groups including al-Qaida in Iraq and the Islamic State of Iraq, UNAMI reported.
The regions most affected are Baghdad and the governorates of Anbar, Salahuddin, Ninewa and Kirkuk.
