A spate of attacks across Iraq killed seven people on Thursday, including three who died when a suicide car bomber struck as recruits were leaving a military base, officials said.

At least one soldier was among three people killed by the car bombing, in the parking lot of a military base in the northern city of Kirkuk, the medical and security officials said.

Another soldier died and two were hurt when a roadside bomb blasted their convoy near the oil town of Baiji, north of Baghdad, while an army captain was killed at a military post in the northern city of Mosul.

Also in Mosul, two civilians were killed in separate attacks on their homes during the night, officials said.

Late on Wednesday, a suicide bomber struck as worshippers streamed out of a mosque in Baghdad, killing 30 people and wounding 55.

The attacks come amid Iraq's worst bloodshed since 2008, with more than 4,000 people killed already this year.
