USA vyřadily v Hormuzském průlivu tanker, Saúdská Arábie bombarduje Jemen

Index ověření faktů: 80/100 — The article's core reported claims—the US disabling a tanker running the Iran blockade, Saudi strikes on Yemen with Houthi retaliation vows, and Houthi strike claims on Saudi Arabia—are accurately drawn from and correctly attributed to the three cited sources, while contextual and analytical assertions rest on prior coverage or outside knowledge not established here.

• US military said it disabled a tanker in the Strait of Hormuz evading a US blockade of Iranian ports — Matches BBC headline/description almost verbatim, including Hormuz and blockade on Iranian ports; correctly cited.
• Saudi Arabia struck targets in Yemen and Houthis vowed retaliation — Directly matches Guardian headline; correctly attributed.
• Houthis said they hit Saudi Arabia in response — Dawn confirms Houthis 'claim strike on Saudi Arabia,' but 'in response' is the article's inference of causation, not stated by the source.
• Saudi strikes on Yemen mark a widening of the war — Guardian headline explicitly frames it as a 'widening of Middle East war'; cited.
• Houthis claimed a strike as the conflict deepened; they vowed further retaliation — Dawn ('conflict deepens') and Guardian ('vow retaliation') both support and are cited.
• Tanker's name, flag and casualties were not immediately available — Consistent with the thin BBC report, which gives no such details, but the absence is asserted rather than sourced.
• The Strait of Hormuz carries roughly a fifth of global oil flow — Plausible general fact but not established by any of the three cited sources.
• Earlier coverage: US strikes into a 13th night with Brent crude breaking $100 — Self-referential to prior article; none of the supplied sources address strike duration or oil prices.
• Only one vessel has been reported stopped; no confirmation the strait is closed — Consistent with sources, which mention a single tanker and no strait closure; appropriately hedged.
• Tanker identity, scale of Saudi strikes/Houthi claims, and Hormuz traffic status are unconfirmed — Accurate characterization—sources provide none of these details, and the article correctly labels them unconfirmed.
