Disgust and outrage dominate Arabic press comment on the Riyadh bombing.
Saudi papers say the attack was a crime against the very religion to which those who carried it out profess their commitment.
"Terrorism presents its ugliness to all" - What are these people targeting, presenting themselves in such a monstrous manner? Who wants to live or deal with a person filled with all this hatred, and possessed with agonies of evil and violent death? They [the perpetrators] have by themselves, and their sinful hands, brought upon themselves social rejection... It is not religious to resort to such ugly methods against the innocent.
Al-Jazeera - Saudi Arabia
"Crime against religion and humanity" - What happened in the residential compound... can only be described as aggression against religion, ethics and humanity... Under which law or legislation are the innocent killed? Under what pretext are innocent children and women assassinated, as they sit in their homes and have not committed any crime?
Ukaz - Saudi Arabia
"Let our courage be in calling things by their true name" - During this period we should be more honest with ourselves, and more courageous in expressing our views. Everyone should declare with sincerity his stance, not on terrorism generally but on terrorists. You are either with the nation, or with terrorism and support destabilising security, as well as terrifying citizens.
Al-Watan - Saudi Arabia
"The dangers of terrorist phenomena" - The world of the extremists is limited in its vision to blood and graveyards.
Al-Riyadh - Saudi Arabia
"Cowardly act of terrorists" - The targeting of a residential area, which shelters families of Arab and Saudi nationals, has nothing in common with the jihad slogan under which radical fundamentalist groups, which carry out such terrorist acts, operate... The time has come for these terrorist groups to wake up and return to their senses and fear of God. The road they are taking will not lead to any good but to more violence, to more killings as well as to ruining the image of Islam.
Al-Rayah - Qatar
"New crime" - What has happened in Riyadh... is an act which shows that violence has reached a dangerous point. It is a situation which signals more confusion in this region, which is currently experiencing unrest.
Al-Watan - Qatar
"Blind terrorism and the Riyadh blast" - How can we describe the bombing which targeted a residential area in Riyadh? Is this not open terrorism and an ugly act which is opposed by any religion, norms and culture? Can we sit back and surrender to the dangers which are facing us after seeing what happened?
Al-Ittihad - UAE
"No time for silence" - Aren't the wild wolves and animals more merciful and humane than the hearts of those who have been brainwashed and are approving what Allah has forbidden? They went on and killed innocent souls. This is one of the biggest crimes... It is not acceptable for anyone to be silent about such crimes... The crimes that took place in Riyadh targeted everyone with no exception... that is why condemning and exposing these operations and their inhuman and illegal nature should be everyone's duty. The one who keeps quiet about this is a dumb devil.
