BAGHDAD — At least three people were killed in attacks in Iraq on Thursday, including a candidate in last year's parliamentary election, security officials said.

In the main northern city of Mosul, unknown gunmen shot dead Raawa al-Obeidi close to her home along with one of her bodyguards, a police captain said on condition of anonymity.

Obeidi ran for election in the March 2010 poll as part of the Sunni-backed Iraqiya bloc, which won the most seats in the election and is now part of the country's national unity government.

She was an administrative official in Mosul's Khansa hospital.

And in the ethnically-mixed city of Kirkuk, also in the north, insurgents attacked and then blew up the home of Turkman MP Arshad al-Salehi, also a member of Iraqiya.

There were no casualties as the lawmaker was not at home at the time, a security official said.

However, two civilians were wounded when a bomb exploded, apparently targeting Kirkuk provincial police chief Major General Jamal Taher Bakr as his convoy returned from an inspection of the decimated house.

It was the second time a senior Kirkuk police official was targeted in a bomb attack in as many months. On April 27, Bakr's deputy was unhurt by four roadside bombs that killed one person and wounded 30 others.

In Baghdad, a bomb in the Waziriyah neighbourhood killed one person and wounded three others, according to an interior ministry official.

Violence in Iraq is down markedly from its peak in 2006 and 2007 but attacks remain common. A total of 211 people died in attacks last month, according to official figures.
