Madina attack was a false flag attack by Saudi regime to show they haven't put their hand in hands of IS...However all of the IS terrorists arrested in Iran have confessed Saudi regime was aiding them and the suicide attacks in Tehran was planed by Saudi. Like fake '9/11 Kaaba', and Saudi made Mena disaster. Saudis love blood of muslims, they have gone out of Islam long before... they love blood of muslims in Pakistan, Afghanistan, Syria, Yemen, Iraq, Bahrain and Shiites all over the world. They love blood.
They offered 1$ million for every bomb explosion in Iran to the terrorists.
Also Saudis are badly supporting IS in Afghanistan to put security of Iran in danger. They directly support wahhabis near borders of Iran in Pakistan.
What has Saudis given to the world other than bleeding?
