A car carrying the family of a cleric was attacked in the Al-Mikdadiye district of Diyala province, 57 kilometers northeast of Iraq's capital Baghdad.
Eight people, including women and children, lost their lives during the attack.
It was stated that the attack occurred as a result of the explosion of a roadside bomb.
A large-scale operation was launched in the region to catch the attackers.
While no one has claimed responsibility for the attack yet; Iraqi security officials think that the terrorist organization Daesh is behind it.
