Iraqi authorities say three people, including two soldiers, have been killed in a pair of attacks targeting the country's security forces.

Police officials say the first attack took place early Tuesday in the city of Fallujah, where a bombing on the house of a police major killed a neighbor and wounded seven people, including four of the officer's relatives.

Fallujah is 65 kilometers (40 miles) west of Baghdad.

In the second attack, police says gunmen shot dead an army officer and a soldier at a security checkpoint in northern Baghdad.

Hospital officials confirmed the casualties.

All officials spoke on condition of anonymity because they were not authorized to speak to the media.

Security forces are a top target for insurgents seeking to destabilize Iraq.
