An explosion set off by insurgents rocked Baghdad today and left 29 Iraqis dead including seven Iraqi policemen. The police were apparently lured into a house to the west of the city and then set off explosives once the policemen were inside the building.

Police officials say they received an anonymous phone call claiming to have information about a place where foreign insurgents were hiding. Once the policemen entered the house, they were ambushed and killed.

U.S. officials believe over 800 kg of explosives were used to create the blast which leveled six homes in the area.

American officials reiterated that these attacks are an attempt by insurgents to disrupt the upcoming Iraqi elections, scheduled for January 30th. They expect attacks to continue and even intensify as the elections draw closer.

There is a concern among American officials about the targeting of Iraqi policemen and security personnel. On Tuesday, 26 Iraqi policemen were killed in separate attacks. The insurgents are actively targeting the government's security forces in an attempt to discourage people from supporting the U.S. backed government.

Most of the violence is in the so-called Sunni Triangle. A top Sunni political party has already announced it would boycott the elections because violence will make it extremely difficult for its supporters to get to the polls. American officials continue to insist that they will do all they can to quell the violence and see that elections take place as scheduled.
