BAGHDAD - Car bombs hit Shiite neighborhoods of the Iraqi capital for the second day in a row Thursday, part of a series of attacks across the country that left 21 people dead.
Baghdad police said the first blast hit a bus and taxi stop during the morning rush hour in the city's eastern Sadr City neighborhood. Nine people were killed, including a 7-year old child, and 16 were wounded in that attack, two officers said.
Another car bomb hit a small market at a taxi stop in Baghdad's eastern suburb of Kamaliya, killing three civilians and wounding 14 others, the officers said.
And in the capital's northern Chikok district, two civilians were killed and 10 were wounded when a car bomb missed a police patrol that was passing through, two other police officers said.
In the northern city of Mosul, a suicide attacker rammed his car into an army checkpoint, killing two soldiers and wounding three others, another police officer said. The attack came just after a car bombing in another area of Mosul wounded two civilians, he said. Mosul is 225 miles northwest of Baghdad.
In Baghdad's southwestern neighborhood of Baiyaa, drive-by gunmen shot and killed a brother of a Sunni lawmaker and wounded two of his guards, two police officials said.
Shortly after sunset, a suicide bomber set off his explosive belt near a Shiite mosque in the ethnically mixed city of Kirkuk after he was prevented by guards from entering. Police said four people were killed and 42 were wounded in the attack that was apparently targeting a funeral inside the mosque.
Medical officials confirmed the casualty figures for all the attacks.
The spike in violence comes amid growing tensions between the Shiite-led government and Iraq's Sunni minority over what they consider second-class treatment. A bloody government crackdown on militants last month in a protest camp in the country's north fueled the latest tensions.
Iraq's embattled Shiite Prime Minister Nouri al-Maliki on Thursday blamed sectarian tensions for the latest attacks.
Incitement could be coming from inside or outside the country, al-Maliki added.
Wednesday's attacks left 33 dead. No one has claimed responsibility, but car and suicide bombings are a hallmark of al-Qaida's Iraq branch.
