Suicide attacks targeting security checkpoints and Shia worshippers have killed 23 people in Iraq.
A suicide bomber rammed his explosives-laden car into a police checkpoint in the town of Youssifiyah, just south of the capital Baghdad, killing three police and four civilians, and wounding another 21 people, police said.
Later on, a suicide bomber driving a pickup loaded with explosives struck a checkpoint manned by police and Shia militiamen near the city of Samarra, killing eight people and wounding 23 others. Samarra and surrounding areas have repeatedly come under attack in recent months by Islamic State. Samarra is 95 kilometres (60 miles) north of Baghdad.
After noon prayers, a suicide bomber set off his explosives belt among Shia worshippers who were leaving a mosque in western Baghdad, killing eight worshippers and wounding 16 others.
IS and other Sunni radicals consider Shias to be apostates deserving of death.
Medical officials confirmed the casualty figures from all attacks.
Iraq sees near-daily bombings and other attacks mainly targeting the Shia majority and security forces. The attacks are often claimed by IS, which seized much of northern and western Iraq last year.
