A suicide car bombing at a police station in the northern Iraqi city of Kirkuk has killed at least seven people and wounded dozens of others.
Iraqi police officials say most of those killed in Monday morning's explosion in a Kurdish section of the city were policemen.
Hundreds of police officers and other Iraqis working with the U.S.-led coalition have been killed in suicide attacks throughout the country over the past several months.
Shortly after the attack in Kirkuk, U.S. Defense Secretary Donald Rumsfeld arrived in Baghdad to meet with American military officials and members of the new Iraqi security force, which is taking over some responsibilities from coalition troops.
The U.S.-trained Iraqi force has 200,000 members, and continues to grow. U.S. officials told Mr. Rumsfeld the Iraqis are making progress, but they will not be ready to take full control of the country's security by June 30, when the United States turns over power to an Iraqi administration.
