Iraqi officials say two separate suicide attacks north of Baghdad have killed at least three people, The Associated Press reported.

A police officer in the city of Mosul says one attacker rammed his explosive-laden car into an army patrol on Monday, June 24, killing a soldier and a police officer. He says seven, including two civilians, were wounded. Mosul is 360 kilometers (220 miles) northwest of Baghdad.

Another officer said a second bomber blew set off his explosive-rigged belt inside a university campus in the city of Tikrit, killing a police officer. The city is 130 kilometers (80 miles) north of Baghdad.

Two medical officials confirmed casualty figures. All spoke anonymously as they were not authorized to release information.

There was no immediate claim of responsibility, but security forces are frequently targeted by al-Qaeda’s Iraq branch.
