Oil prices gained nearly 1% during Tuesday's trading session as market participants reacted to potential supply shortages stemming from ongoing political tensions in the Middle East. Brent crude futures for December delivery rose by 0.75% to $110.37 per barrel, while West Texas Intermediate crude for November delivery climbed 0.43% to $104.11 per barrel. The upward trend follows announcements from Houthi rebels in Yemen regarding attacks on critical Saudi infrastructure, including Aramco facilities, the Shaybah oil field, and airports in Riyadh and Abha.
