Coordinated bomb attacks killed more than 32 people across Iraq on Sunday.
According to CNN, the bombings make it the country's deadliest day in nearly a month.
There were seven blasts in and around Baghdad, killing 20 people, CNN also said. At least 37 other people were wounded in the explosions in the city center, the Baghdad neighborhoods of al-Mashahda and al-Amel, and the nearby city of Taji. A car bomb later exploded near a Shiite shrine in al-Madaan, killing four people. Nineteen other people were wounded.

And in Kut, a predominantly Shiite city, six people, including three Iraqi police officers, were killed and 10 people were injured in a car bomb explosion at a police checkpoint.
No group claimed responsibility for Sunday's attacks, but a local al Qaeda affiliate and other Sunni Islamist groups have claimed at least one big assault a month since the last American troops left the country in December, reported Reuters. Violence in Iraq has slowed since the 2006-2007 fighting, but Sunni Islamists still launch frequent attacks in order to prove they remain a threat and to undermine the Shia-led government, which claims to provide security.
Reuters also reported that the last big attack was on September 9, when a series of bombs in mainly Shia districts killed more than 100 people across the country.
