Nov 9 (Reuters) - Saudi Arabia's huge East-West oil pipeline was ​struck in the Medina region, state ‌media reported on Monday, citing an energy ministry source.

The person said the attack caused a limited ​fire that has since been extinguished. ​It caused no fatalities or injuries, ⁠and pipeline operations have not been ​affected, the person added.

The 1,200 km (745-mile) pipeline runs ​through the desert across the Arabian Peninsula and was shut down for several days in September after drone ​attacks, which Saudi Arabia blamed on ​Iraqi militias.

Since conflict in the Middle East disrupted oil ‌flows ⁠through the Strait of Hormuz, Riyadh has rerouted about 4 million barrels per day of crude via the East-West Pipeline ​to Yanbu, ​equivalent ⁠to about 4% of global supply.

The pipeline has spared Saudi ​Arabia, the world's biggest exporter, from ​the ⁠brunt of the impact of the wartime shutdown of the Strait of Hormuz ⁠that ​has crippled exports from ​its neighbours.
