Three Iraqi people were killed, two others wounded, and 16 more detained, including a dean of a college, in separate bomb attacks and gunfire in the provinces of Salahudin and Diyala on Tuesday, police said, Xinhua reported.
Two policemen were killed when unknown gunmen opened fire on a police checkpoint in the Aziz Balad area, some 100 km north of Baghdad, a provincial police source told Xinhua on condition of anonymity.
Separately, an Iraqi security force killed a suspected insurgent and detained eight people during a raid on the al-Mu' atasim area, some 110 km north of Baghdad, the source said.
The raid was based on intelligence reports which said that an armed group was planning to carry out a suicide bombing on the house of a senior official in the area, the source added.
In Diyala, an anonymous provincial police source told Xinhua that two civilians were wounded when a motorcycle bomb exploded near a primary school in the al-Mu'alamin neighborhood in western the provincial capital city of Baquba, some 65 km northeast of Baghdad.
The powerful explosion also destroyed three civilian cars and caused damages to five nearby buildings and shops, the source said.
Also in the province, Iraqi security forces detained professor Adnan al-Mahdawi, dean of the Education College in Diyala University, the source added.
Mahdawi and two people who were accompanying him in his car were detained at a checkpoint in an area northwest of Baquba, the source said.
Five more suspects were detained by Iraqi security forces during search operations in different areas of the province, the source added.
Diyala province, which stretches from the eastern edges of the capital to the Iranian border east of the country, has long been a stronghold for al-Qaida militants and other insurgent groups since the U.S.-led invasion of Iraq in 2003, despite repeated U.S. and Iraqi military operations against them.
Sporadic attacks continue in Iraq as part of recent deterioration in security which shaped a setback to the efforts of the Iraqi government to restore normalcy in the country after more than four months of U.S. troops pullout of cities and towns.
