At least seven people have been killed and 23 others hurt in a double bomb attack near a music shop in a market in central Baghdad.
Police said that officers and civilians were among the casualties. A crowd had gathered near the shop after one bomb exploded and then a second device went off.
The attack took place in an area where suicide bombers have killed police, security forces and labourers in the past. Insurgents have frequently lured police and civilians to one bomb site and then attacked them with another bomb.
Three people were killed and four wounded in three other incidents across Iraq today.
South of Baghdad in Yusifra, two people were killed when a roadside bomb went off on a highway. Also south of Baghdad, in the city of Basra, four policemen were wounded when a roadside bomb targeted their patrol.
And in a shooting in Fallujah west of Baghdad, gunmen killed Kamal Shakir al-Nazal, the head of Fallujah city council and the preacher of its main mosque, while he was heading to his work.
Meanwhile, the US military has said that three marines were killed yesterday by a roadside bomb in the town of Hit, west of Baghdad, and that another marine died of his wounds after a separate roadside bomb attack in the Anbar province of western Iraq on Sunday.
In a separate development, US and Iraqi military officials said that Iraqi soldiers had captured 63 suspected insurgents, including 12 Syrian nationals, in Tal Afar, Ramadi, Basra and Salman Pak yesterday.
