A suicide car bomb attack against a security checkpoint north of Baghdad has killed at least nine people.
Ali al-Hamdani, a spokesman for Salahuddin province, said the suicide bomber rammed his explosives-laden car during rush hour on Sunday into the main checkpoint at the southern entrance of the provincial capital, Tikrit.
Five female students, a woman and three policemen were killed. He added that 25 other people were wounded.
No group has claimed responsibility for the attacks, but Islamic State militants have claimed multiple similar attacks.
At least 11 people were killed in a separate suicide attack against Shiite pilgrims north of Baghdad.
The spokesman for Salahuddin province, Ali al-Hamdani, says Sunday's attack took place in the city of Samarra, 60 miles north of Baghdad, where a revered Shiite shrine is located.
He said the bomber parked his explosives-laden ambulance in a car park and walked up to the pilgrims who had just left their buses and were heading to the shrine about 500 yards away. He first detonated the car and then blew up himself.
Up to 100 others were wounded, he said.
