A militant wearing a suicide vest struck an intelligence bureau in northern Iraq on Tuesday, wounding at least three members of the security personnel, Iraqi officials said, blaming the attack on the Islamic State group.

A number of attacks in Iraq’s bordering province, especially Diyala along the Iranian border, have raised concern. Islamic State fighters have filmed themselves with weapons that appear to be of Iranian origin, while security gaps remain due to tension between the KRG and Baghdad.

Militants linked to the Islamic State (IS) terror group have increased their attacks in recent weeks against military forces and civilians in the desert region of Syria.
