UKMTO Warning 133-26 reported at 1910 UTC Sep 10 that four unknown projectiles struck two unidentified vessels 4 nm west of Khasab, Oman, setting one ablaze; the master of a third vessel saw the impact from 6 nm away [1]. UKMTO has not attributed the attack to any party, though Iran has conducted all similar strikes in this area of the strait [1][2]. Khasab sits on Oman's Musandam Peninsula at the Hormuz gateway, and repeated attacks there could further deter commercial shipping and raise war-risk premiums [2].

Iran's IRGC said it targeted a Saildrone Explorer USV in the Strait of Hormuz on Sep 11, calling it an aggressive mission; the US gave no immediate confirmation [3]. CENTCOM reported redirecting 96 commercial vessels under its blockade as of Sep 10 [3].

Brent rose above $106 on Sep 10 per Ship & Bunker [1] and to $108–$109 by day's end per Maritime Executive [4]. LSEG data cited by analysts show transits at their lowest since May, about ten ships/day, with no VLCC leaving the Gulf for almost a week [1]. Commercial transits on Sep 6 were 6 vessels versus typical 85/day [4].
