(CNN) -- At least 11 people were killed in a bombing in Diyala province Wednesday morning, police said.
Iraqi soldiers received a tip about insurgents hiding in a house in al-Saadiya. When they raided the house, it exploded, authorities said.
Police believe the house was booby trapped.
At least eight Iraqi soldiers were killed, three civilians in a nearby house were also killed. Four soldiers were wounded.
The bombing comes amid political uncertainty and increased attacks across Iraq .
Iraqi politicians have been unable to form a government more than five months after the country's inconclusive national elections.
There have been concerns that insurgents would take advantage of the political vacuum to try and reignite the sectarian bloodshed that gripped Iraq for years.
U.S. forces plan to continue their drawdown ahead of President Barack Obama's August 31st deadline for ending all combat operations and keeping a residual force of 50,000 troops with a mission limited to stability operations, and advising and assisting Iraqi security forces.
Current U.S. troop levels are at just under 60,000 compared with a peak of around 170,000 during the surge in 2007.
