BAGHDAD, Iraq, Sept. 10 (Xinhua) -- Sixteen people were killed and 32 wounded in separate shootings and bombings in Iraq's northern province of Niniveh and eastern province of Diyala, the police said on Tuesday.
In the northern province of Niniveh, four people were killed and five others wounded in separated shooting and bombings, a local police source told Xinhua on condition of anonymity.
Three out of the five attacks took place in Mosul, capital of Niniveh province, some 170 km north of Baghdad, the source added.
Earlier in the day, 12 people were killed and 27 injured in separate bomb attacks in Iraq's eastern province of Diyala.
In one attack, five people were killed and 13 wounded when a car bomb detonated near a coffee shop in a village near the provincial capital city of Baquba, some 65 km northeast of the Iraqi capital of Baghdad, the source told Xinhua on condition of anonymity.
In a separate incident, three people were killed and five wounded in a roadside bomb explosion near their car in Baquba's eastern suburb of Bawiyah, the source said.
Meanwhile, a roadside bomb went off at a marketplace in the village of al-Salam, some 30 km northeast of Baquba, killing four people and wounding nine others, the source added.
Diyala province, which stretches from the eastern edges of Baghdad to the Iranian border, has long been a volatile area since the U.S.-led invasion of Iraq in 2003 despite repeated military operations against militant groups.
Iraq is witnessing its worst eruption of violence in recent years, which raises fears that the country is sliding back to the full-blown civil conflict that peaked in 2006 and 2007, when monthly death toll sometimes exceeded 3,000.
