Why did a man burn down a mosque?

A man was arrested Sunday for setting fire to a mosque in a small town in northern Iraq, killing at least 18 people, police and the Kurdistan Region’s police said.

The man allegedly drove a pickup truck and then parked it next to a small mosque in the village of Makhmur on the outskirts of the northern city of Kirkuk, police spokesman Sheikh Ali Karim said.

Police found him in the truck and he was taken into custody.

No one was injured in the attack.

The attacks on Friday and Saturday were among at least 23 suspected suicide bombings in Kirkuk since January, which police said were the deadliest in the province in recent years.

Police have arrested 13 suspects, and more than 1,000 others have been detained in connection with the attacks.

The Islamic State group has claimed responsibility for the attacks, saying they were carried out to draw attention to Kurdish demands for greater autonomy for their autonomous region.

Kurdish President Masoud Barzani said the attack was a sign that the extremist group is losing the support of the Iraqi Kurdish people and that it was time to fight back against it.
