After ~23:53Z on 26 Sep 2026, hormuzletter (citing initial reports and a senior Iranian source) claimed Iran began laying naval mines in the US-backed southern Omani corridor of the Strait of Hormuz, saying at least some of 10+ missiles fired tonight carried mines. A Pravda EN mirror (~00:22Z 27 Sep) attributed the same claim to Middle East Spectator Telegram, noting unclear mine counts and whether deployment succeeded. No UKMTO numbered warning in-window; treat as unverified claim distinct from earlier Sirik/Hormuz explosion/multi-vessel event evt_cc26554a.
