Twenty-two people were killed and 24 others wounded in separate violent attacks across Iraq on Thursday, police and medical sources said.
In northern Iraq, gunmen broke into a house of a policeman in south of the city of Mosul, and shot dead the policeman, his brother and one of his relatives, before they fled the scene, a local police source told Xinhua on condition of anonymity.
In a separate incident, a car bomb went off near a police patrol in the western part of Mosul, leaving two policemen and three passers-by wounded, the source said.
Meanwhile, gunmen opened fire on a police vehicle on a main road near the city of Baiji, some 200 km north of Baghdad, killing a police officer and a policeman, and wounding another, a local police source told Xinhua.
Near Baghdad, a police officer was killed and four policemen were wounded when a roadside bomb struck their patrol in Rashdiyah area, a police source said.
In Anbar province, gunmen believed to be linked to the Islamic State in Iraq and Levant (ISIL), an al-Qaida breakaway group in Iraq, attacked a checkpoint manned jointly by policemen and members of a government-backed Sahwa paramilitary group in the provincial capital city of Ramadi, some 110 km west of Baghdad, killing two policemen and wounding two others and two Sahwa members, a provincial police source told Xinhua.
Also in Ramadi, a gunman was killed when four roadside bombs detonated prematurely in his car while he was driving in the western part of the city, the source said.
Separately, anti-government gunmen attacked an army base in Haswa area just east of the militant-seized city of Fallujah, some 50 km west of Baghdad, leaving three soldiers killed and five others wounded, along with destroying three military vehicles, the source added.
In addition, seven people were killed and five wounded by artillery and mortar shelling on several neighborhoods in the besieged city of Fallujah, a medical source from the city hospital told Xinhua.
Anbar province has been the scene of fierce clashes that flared up after Iraqi police dismantled an anti-government protest site outside Ramadi in late December last year.
In Iraq's eastern province of Diyala, Iraqi security forces carried out an operation targeting ISIL militants in Himreen area in north of the provincial capital city of Baquba, some 65 km northeast of Baghdad, a provincial police source told Xinhua.
The operation resulted in the killing of the provincial leader of ISIL Abu Anas al-Shami and two of his aides, the source said, adding that the gunmen are accused of carrying out attacks against the security forces and civilians.
