The Iraqi security forces arrested eleven suspects over a deadly car bomb attack in the eastern province of Diyala, which killed at least 100 people and injured 150 others.

The forces managed to nab eleven people out of 14 wanted during a crackdown, Dijla Operations Commander Lieutenant General Abdul Amir said.

At least 930 displaced Iraqi families have returned homes in the city of Diyala while 500 others would return on Saturday, he said.

Meantime, the interior ministry said a five-member terror group was arrested over exploding two vehicles during the holy month of Ramadan, he added.
