A spate of attacks in Baghdad and north of the capital killed at least 45 people on Monday, security and medical officials said, in an updated toll of earlier attacks.

At least 112 people were wounded in the shootings and bombings, totalling more than a dozen separate attacks, some of which involved coordinated explosions, shattering a relative calm in recent weeks.

The deadliest attack struck the town of Taji, just north of Baghdad, where 18 people were killed and 29 wounded in a series of explosions.

All of the attacks were either in Baghdad or north of the capital.
