Iran vows 'full-scale' offensive as US strikes enter seventh night and hit civilian targets

Fact-check index: 58/100 — The core claims about the seventh US strike, Iran's conditional 'full-scale' threat, and renewed attacks on Gulf states are properly sourced, but much surrounding detail (civilian-infrastructure strikes, Strait of Hormuz framing, prior escalation warning) is unverified extrapolation not found in the two thin sources.

• US launched a seventh consecutive night of airstrikes overnight into Friday — France 24 explicitly states the US launched a seventh wave of airstrikes on Iran overnight on Friday; correctly cited.
• Iran threatened to resume 'full-scale offensive operations' if attacks continued — France 24 quotes this exact phrasing and the conditional ('if the attacks continued'); the article accurately reflects the conditional nature.
• Iran renewed/resumed attacks on Gulf states after the latest US wave — Reuters headline states 'Iran renews attacks on Gulf states after another night of US strikes'; cited correctly, though only a headline is available.
• Tehran's warning marks a shift from responding to specific sites toward open-ended retaliation — Interpretive framing; neither source describes a prior pattern of responding to 'specific sites' to establish this shift.
• US strikes had begun reaching civilian infrastructure inside Iran — Attributed to the outlet's own earlier coverage, not to the two provided sources; France 24/Reuters snippets say nothing about civilian infrastructure.
• Tehran had already warned it would escalate if the campaign did not stop (before this update) — Consistent with the France 24 conditional threat, but the 'already/earlier' framing relies on the outlet's prior article, not the given sources.
• The fighting is concentrated around the Strait of Hormuz — Neither source mentions the Strait of Hormuz or the location of fighting; this is added geographic context.
• The Strait carries a large share of the world's seaborne crude oil — Generally true as background knowledge, but not established by or cited to either source.
• Confrontation now extends beyond a bilateral US-Iran exchange to include third countries — Reasonable inference directly from the Reuters headline that Iran attacked Gulf states.
• The threat is conditioned explicitly on attacks continuing (interpretation) — Accurately restates the France 24 conditional; the interpretive 'demand to stop' is labeled as hypothesis.
• Source does not specify which Gulf states, targets, casualties, or US/Gulf response — Accurate self-assessment; the Reuters snippet is headline-only and France 24 gives no such detail, so the warn callout is a correct limitation disclosure.
