A car bomb and several roadside blasts killed three people and wounded dozens in Baghdad on Wednesday morning, health and security officials said.
In the deadliest attack, a vehicle packed with explosives was detonated and quickly followed by a roadside bomb near a bus terminal in the south Baghdad neighbourhood of Bayaa, killing two people.
Officials from the ministries of defence and interior, who spoke on condition of anonymity, said more than 20 others were wounded, including 10 members of the Iraqi security forces.
And on Al-Sheikh Omar street in the centre of the capital, two near-simultaneous roadside bombs killed one person and wounded a dozen others, the interior ministry official and a doctor said.
The unrest comes a day after two American soldiers were gunned down by an Iraqi comrade following a row over a sports match, US and Iraqi military officials said.
