According to Al-Alam News Network, the protests were held yesterday afternoon (on Saturday) with the wide presence of people. Participants in the demonstration condemned the terrorist attack on the Mosque of "Imam Ali" (peace be upon him).

The need to the formation of popular committees, in order to secure the areas, stressed.

This area has witnessed two other mass protests in recent days against the terrorist attack.

Last Friday, a Saudi terrorist during Friday Prayers in the Mosque "Imam Ali" (peace be upon him) in "Al-Qadih" blew up himself. At least 20 people martyred and about 100 were injured in the terrorist attack.

The terrorist group ISIS took responsibility for the explosion.
