A fire erupted at a petroleum industrial site in Fujairah, UAE, following a drone attack from Iran. S. oil rising over $3 and Brent increasing over $5.

News of the Fujairah attack has not yet been officially confirmed by Iran, according to Tasnim News. The fire marked a significant escalation in regional tensions, with the attack reported by UAE's Fujairah authorities. South Korean government officials are checking into reports that a South Korean-flagged vessel has been struck in the Strait of Hormuz, as stated by the South Korean Yonhap News Agency.

This potential incident adds to the series of maritime disruptions in the area. The most recent reported attack in the region occurred at 1940 UTC yesterday, according to the United Kingdom Maritime Trade Operations Center (UKMTO). That timing places the event just before the latest developments in Fujairah and the Strait of Hormuz.

U.S. official denied Iranian claims that a warship was struck by Iranian missiles, according to an Axios report. This denial counters narratives emerging from the ongoing conflicts in the region.
