By Nic Robertson, Hira Humayun, CNN(CNN) — Saudi Arabia is bracing for a “multiple coordinated attacks” by Iraqi militias factions and Iran-backed Houthis, a Saudi official told CNN, as the broader Middle East conflict threatens to widen. In the past few weeks, Saudi Arabia has come under missile attacks from the Houthis in Yemen and drone attacks from Iran-backed militias in Iraq. “Saudi Arabia will take all necessary measures to deal with any aggression,” the official said. The Saudi official said Saudi Arabia had detected meetings involving Iraqis, Houthis and some IRGC members, as well as the movement of drones and missiles. Despite the reports, the official said Saudi Arabia would continue its de-escalation efforts and contacts with Iraqi authorities.
