Putin threatens to seize EU ships after Ukraine hits key Russian port

Fact-check index: 72/100 — Core facts about Putin's seizure threat, the Novorossiysk drone attack, the sanctions-retaliation framing, and falling grain exports are all supported by the cited sources, but several analytical claims (NATO-adjacent framing, insurance risk premiums, global food price impact, 'hours after' timing) are added interpretation not established in the source material.

• Putin threatened to seize EU-flagged vessels from the Black Sea to the Pacific — Directly matches Fox News subhead: 'Putin threatened to seize European vessels from the Russian Black Sea to the Pacific.'
• Ukrainian drone attack crippled grain-loading facilities at Novorossiysk — Matches Fox News ('Ukraine's drone attack crippled Novorossiysk grain terminals') and BBC ('Major Russian grain export terminal hit in Ukraine Black Sea port attack').
• Novorossiysk described as the Black Sea Fleet's 'last major stronghold' — Matches Fox News headline phrase verbatim.
• Threat came 'hours after' the drone attack — Sources establish the threat followed the attack but do not specify an 'hours after' timeframe; this precise timing is not confirmed by the provided source excerpts.
• Moscow cast threatened seizures as retaliation for a new round of EU sanctions — Matches RFI headline: 'Russia threatens retaliatory seizures of EU ships amid new sanctions push.'
• Grain exports from both Russia and Ukraine are falling as each side strikes the other's port infrastructure — Matches BBC: 'Grain exports from both Russia and Ukraine are falling as both countries attack each other's shipping facilities and ports.'
• Threat marks a shift from covert sabotage to open coercion against commercial shipping, referencing a 'NATO-adjacent bloc' — This is the article's own analytical framing; none of the three cited sources characterize the EU as 'NATO-adjacent' or frame this as a shift from covert to overt tactics.
• Raises risk premiums for insurers/shippers and could affect global food prices — Plausible economic inference but not stated or sourced in any of the three articles provided.
• What to watch: whether Russia acts against a specific vessel, EU response, further rerouting of Russian grain exports — Forward-looking editorial speculation not drawn from factual reporting in the cited sources.
