A spate of roadside bombs killed seven people and wounded three in Iraq's volatile Diyala province on Saturday, Iraqi security officials said.
The attacks came a day after a 24-hour traffic ban was enforced in major cities in Diyala, one of the most dangerous provinces in Iraq, in a bid to curb violence.
Police Major Ahmad Hassen said six people were killed when their minibus was blown up by a roadside bomb near the town of Al-Sadiyah, 100 kilometres (62 miles) northeast of the provincial capital Baquba.
"Three men, two women and a child were killed," Hassen told AFP, adding that another two men and a woman were wounded in the blast.
In Baquba itself, a roadside bomb killed one person and wounded another, said army Major Ahmad Ibrahim.
When members of an anti-Qaeda front arrived to help the wounded, another bomb went off and wounded two people, he said.
Friday's one-day curfew was imposed in Baquba and in the province's other main towns of Al-Khalis and Al-Muqdadiyah "with the aim of curbing the violence," military operations chief Brigadier General Raghib al-Omeiri said.
"The three cities under curfew are the most volatile places in Diyala province and have been witnessing violent actions on an almost daily basis," Omeiri told AFP.
