**Three blasts have rocked the Iraqi city of Ramadi, west of Baghdad, killing at least 23 people and wounding several others, police have told the BBC.**A car packed with explosives ploughed into a concrete wall at the main police headquarters. Another suicide attacker later detonated a bomb on a motorcycle.
The third blast, an apparent car bomb, went off outside a hospital.
Ramadi is the main city of the western province of Anbar, formerly one of the centres of the Sunni insurgency.
But violence in the region has decreased sharply over the past two years, as tribal leaders deserted the militants and backed US-led and government forces.
The dead and injured in the latest attacks include both police and civilians.
A curfew has been imposed in Ramadi.
