据伊朗劳工通讯社（ILNA）报道，根据英国海上贸易行动办公室的数据，过去7天内，约有12起船舶或油轮遭袭或被锁定为目标的事件。在此期间，约有254艘船舶通过霍尔木兹海峡，平均每天约36艘。该机构还报告称，累计记录了84起相关事件，其中74起涉及抛射物袭击。约四分之三的袭击发生在海峡南部航道。但实际发生的事件数量可能高于已公布的数据。约旦军事与战略专家、上校纳达尔·阿布扎伊德认为，部分船舶不愿报告受损情况，可能有两个原因：一是出于经济考虑，尤其是保险及相关成本；二是出于安全和军事方面的考量，以避免暴露油轮使用的航线。阿布扎伊德表示，公布船舶航行路线等信息，可能使外界更容易识别其航行规律，并增加这些船舶未来遭到袭击的风险。

Russian UAVs were confirmed to have struck 22 locations; wreckage from downed UAVs was found at three additional sites.

Iran’s Islamic Revolutionary Guard Corps Navy said on social media on the 17th that a "second supertanker" struck a mine, exploded and caught fire in the Strait of Hormuz.

The IRGC reiterated that the "Strait of Hormuz is closed."
