A series of bombs in and around the Iraqi capital killed 10 people on Sunday, and an intelligence official warned of a campaign to undermine security before a much anticipated meeting of Arab heads of state in March.
The senior Iraqi official also said insurgents appeared to be taking advantage of the government's delay in appointing a new interior minister, who runs the nation's security forces.
The three-hour drumbeat of explosions began around 7 a.m. in Baghdad's rush hour at the start of the local workweek. Besides the dead, 34 people were wounded. The attacks appeared to involve roadside bombs, suicide bombers and car bombs.
No group immediately claimed responsibility.
