Saudi Arabia Draws 'Red Line' Over Mecca Attack by Iran-Backed Houthis

The kingdom, a key US ally, needs safe outlets for its crude and military assistance as the region responds with condemnation but no sign of military support.

Oil prices remain above $100 a barrel, and crucial Saudi pipeline has been shut down for weeks after an attack by Iranian-backed militias in Iraq.
