Húsíové vyhlásili okamžitou „námořní blokádu" Saúdské Arábie

Index ověření faktů: 88/100 — The article accurately reports the BBC-sourced embargo declaration and rigorously flags its own speculative and unconfirmed elements, though several contextual geographic claims go beyond the thin source material.

• Houthis announced an immediate maritime embargo on Saudi Arabia — Directly matches the BBC headline and body, correctly cited.
• Embargo takes effect immediately, framed as response to a Saudi blockade of Yemeni ports and airports — Matches the BBC snippet verbatim in substance: 'begins immediately and is a response to a Saudi blockade of ports and airports in Yemen.'
• Scope, enforcement, and covered waters were not specified — The source provides no such detail, so the article's stated absence is accurate and appropriately hedged.
• Houthis control Sanaa and much of northern/western Yemen including the port of Hodeidah — Widely accurate background knowledge but not established by the provided BBC source material, which contains only the headline and one sentence.
• The coast sits beside the Bab al-Mandab strait linking the Red Sea to the Gulf of Aden and Suez route — Geographically correct context but drawn from general knowledge, not the cited source.
• The group has previously targeted commercial shipping in these waters — True in the real world but unsupported by the source material supplied for this report.
• Two-chokepoint risk premium / Hormuz strain / oil-price effects — Explicitly labeled a hypothesis and projection by the article itself; source confirms none of it, and the article says so.
• Reports of Brent crude above $90 and a parallel Hormuz conflict — Article transparently flags these as unconfirmed and not established by the source; correctly not asserted as fact.
• No Saudi response, shipping-industry reaction, or market impact established — Accurately characterizes the limits of the source material.
