A suicide bomber killed five police in Iraq on Tuesday, an officer and a doctor said, as an Al-Qaeda front group claimed a wave of deadly bombings.
The attack in Tikrit, which hit the counter-explosives police headquarters for Salaheddin province, also wounded seven police.
The bombing came a day after 13 bombs in and around Baghdad killed at least 50 people.
Most targeted Shiite-majority areas and an Al-Qaeda front group said it had carried out coordinated bombings.
"The security sections of the State of Baghdad simultaneously hit selected targets that had been chosen carefully," Al-Qaeda front group the Islamic State of Iraq and the Levant said in a statement on the Honein jihadist forum.
