Ruská raketa přeletěla do Polska, noční útok na Ukrajinu zabil osm lidí

Index ověření faktů: 78/100 — Most core facts (airspace breach, barrage scale, casualties, Zelensky/EU reaction) are well-supported by the cited sources, but the article overstates certainty by calling the Kh-101 missile identification 'confirmed' when Fox News still labels it 'suspected'.

• Poland confirmed a Russian missile breached NATO airspace — Matches Al Jazeera ('Poland says Russian missile breaches NATO airspace') and ABC News ('Russian missile violated NATO airspace in Poland, Kyiv says').
• The object was specifically a Russian Kh-101 cruise missile, now confirmed — Fox News describes it as a 'suspected Russian Kh-101 missile' — the type itself is not confirmed in any cited source, only the general fact of a missile breach; article overstates certainty.
• Overnight barrage of 70+ missiles and 280 drones killed at least 8 people — Directly matches Fox News figures.
• Poland scrambled fighter jets in response — Stated in Fox News headline and body.
• Earlier report described a 10-metre-wide crater in eastern Poland with cause not yet stated — Matches France 24 report on the crater.
• Kyiv separately corroborated the airspace violation — ABC News headline explicitly attributes the claim to Kyiv ('...Kyiv says').
• The missile that crossed into Poland was part of a strike aimed at the Lviv region near the Polish border — Matches France 24: Russia 'staged a massive new attack on the Lviv region in western Ukraine, near the border with Poland.'
• Zelensky urged allies to supply anti-ballistic missile systems, calling it 'Russian terror' — Matches France 24 clip description.
• The EU condemned the attack — Matches France 24: 'the EU has slammed the attack.'
• Poland has not disclosed further details of its military response beyond scrambling jets — Not stated or denied in any cited source; appears to be an inference rather than a sourced fact.
• This is the kind of incident NATO's Article 4 consultation clause exists for / hypothesis about Russian intent — Explicitly framed as the article's own hypothesis/analysis rather than a sourced fact, and appropriately hedged, but not itself established by any cited report.
