IsIs strikes a holy site

Medina bombing is an assault on Islam itself (Opinion)

(Vision)A wave of suicide bombings hit three Saudi Arabian cities over a 24-hour period.

The attacks came on the heels of massive jihadi assaults in the Muslim world last week that have been been tied to ISIS; analysts believe that this string of assaults in Saudi Arabia could be the work of the terror group.

There has been no claim of responsibility.

Two of the attacks failed but four people were killed in the third, all of which appear to be coordinated -- targeting both Saudi security forces and Western interests.

The first occurred before dawn near the U.S. Consulate in Jeddah. The attacker killed only himself after detonating an explosive according to the state-run Saudi Press Agency. Policemen were injured in the attack.

The Saudi Interior Ministry identified the Jeddah bomber as Pakistani national Abdullah Qlazar Khan.
