A series of gun and bomb attacks has racked Iraq for the second straight day, with unidentified gunmen targeting a military base and car bombs exploding in Baghdad, Kirkuk and elsewhere.

More than 100 people are reported to have been killed and 180 injured in at least 19 separate explosions and attacks on Monday morning, officials said.

At least 15 Iraqi soldiers were killed and four others injured after gunmen attacked a military base in Salah Din province, an army official told Al Jazeera.

The attack took place early on Monday morning, while the soldiers were still asleep, in a base east of Dhuluiyah township, about 90km north of Baghdad. No group has yet claimed responsibility for the attack.

A car bomb in the city of Taji, north of Baghdad, targeted a residential compound. Initial reports suggested that more than 18 people had been killed, and dozens wounded. That attack involved a secondary explosion, which targeted rescue personnel who had rushed to the scene.

In the northern oil town of Kirkuk, police were targeted by four synchronized car bombs, killing five people, including three civilians. Nineteen people were injured in those blasts.
