International oil markets opened Wednesday with renewed concern over Saudi Arabia’s energy infrastructure.

Reuters reported that Brent crude rose 1.3% to $115.36 per barrel at 01:40 GMT, while US WTI increased 1.22% to $101.12.

The rise followed Ansar Allah’s announcement Tuesday that it had struck Saudi Arabia’s Ras Tanura refinery with a missile.

The refinery has a processing capacity of approximately 550,000 barrels per day.

Saudi authorities had not independently confirmed the claimed missile strike, and no verified new production-loss figure was available.

The price increase reversed part of Tuesday’s decline, when diplomatic activity had temporarily reduced fears of supply disruption.

Strategic assessment: The conflict is placing pressure on both Saudi Arabia’s Gulf energy infrastructure and its Red Sea export alternatives. Any confirmed, sustained disruption would carry consequences far beyond the battlefield.
