At least 10 Iraqi police officers died and five others were wounded Tuesday in three separate attacks, a security official told Efe.
Seven of the officers died in one attack mounted by unknown assailants who opened fire with machineguns on a patrol east of Samarra, 120 kilometers (74 miles) north of Baghdad.
In a similar attack, three other officers died and three were wounded near the town of Amam Wais, in the eastern portion of Diyala province.
The source added that two other police officers were wounded in another attack with the same characteristics in the Diyala town of Abu Saida, and there security forces managed to arrest four of the attackers.
Iraq has been experiencing a resurgence of sectarian and political violence that in 2013 took the lives of 8,868 people, 7,818 of them civilians, according to U.N. figures.
In addition, for the past week the western province of Al Anbar, which represents one-third of Iraq's national territory, has been the scene of military operations by the Iraqi army against armed groups, including the Al Qaeda-linked Islamic State in Iraq and the Levant, which is also active in neighboring Syria.
