More than 30 people have been killed in an attack by suspected Islamic State militants in the Iraqi city of Tikrit, the BBC reported.
A police source told the BBC that the militants targeted officers in the central Zuhur district overnight, and then opened fire at civilians nearby, BBC added.
At least two of them detonated suicide belts during clashes with police, which could still be heard after sunrise, according to the BBC.
No group has claimed it was behind the assault, but IS has launched a number of similar attacks in recent months.
It also comes as government forces continue an offensive to retake Mosul, 185km (115 miles) to the north, the last major IS stronghold in Iraq, added the BBC.
Police Colonel Khalid Mahmoud told Reuters news agency that about 10 militants dressed in police uniforms were involved in Tuesday night’s attack, explained the BBC.
