US-Iran tensions escalated as President Trump threatened to bomb Iranian bridges and power plants if attacks on shipping continue, while Tehran warned it would target regional infrastructure in response, raising fears of a broader conflict. Yemen's Houthi rebels claimed attacks on Saudi oil tankers and declared a maritime blockade, prompting shipping diversions and heightening the risk along the Bab al-Mandeb chokepoint. Industry and maritime analysts say the Red Sea disruptions are already forcing vessels to reroute toward the Suez Canal and pushing up insurance costs, intensifying the pressure on global energy flows. Oil markets reacted with Brent trading around the mid-90s per barrel as traders priced in further supply disruptions from the Hormuz and Red Sea corridors. Security authorities, including UKMTO, warned of escalating risks to shipping across the region, underscoring the potential for wider regional escalation. The upheaval is shaping broader geopolitical and economic consequences, with energy supply routes under strain and markets jittery amid multiple actors and retaliatory threats.
