Saudi Arabia has shut down its East-West pipeline, after the vital oil conduit came under aerial attack in the widening Middle East war, ​threatening to send energy prices even higher, Reuters reported. 

The world’s largest crude oil exporter said it temporarily closed the pipeline as a precaution after a drone attack that both Baghdad and Riyadh said had originated in Iraq, where Iranian-backed militias operate. Iraq dismissed a military commander on Saturday in response to the attack.
