Baghdad rocked by explosions

At least 20 people have been killed and scores more injured by a series of explosions across the Iraqi capital, Baghdad.

Several car bombs and improvised explosive devices went off in mainly Shia neighbourhoods, apparently targeting busy locations such as markets.

Sunni insurgents linked to al-Qaeda have been blamed for a recent spike in violence, but no group has yet claimed responsibility for the bombings.

The BBC's Nahed Abouzeid in Baghdad says the suspicion is that the attacks were planned to cause as much harm as possible.
