US and Iran trade strikes as Washington reimposes oil sanctions, crude climbs

Fact-check index: 88/100 — Nearly every substantive claim is drawn directly from the cited headlines and properly attributed, though some specifics (base names, crypto reaction) rest on a single source and intent claims are correctly flagged as inferred.

• US launched new strikes against Iran and reimposed oil sanctions — Matches UPI headline 'United States launches new strikes against Iran, reimposes sanctions' and NYT 'U.S. Strikes Iran and Blocks Its Oil Sales'; cited to UPI.
• The two sides traded fire in the biggest test of a recent truce — Directly matches CNN headline 'US and Iran trade strikes in biggest test of truce as NATO leaders meet'; cited to CNN.
• US reimposed measures to block Iranian oil sales — Matches NYT headline 'U.S. Strikes Iran and Blocks Its Oil Sales'; cited to NYT.
• Oil prices surged amid the conflict and sanctions — Matches Devdiscourse headline 'Oil Prices Surge Amid Middle East Conflict and Sanctions'; cited to Devdiscourse.
• Iran struck US bases in Bahrain and Kuwait, rattling crypto markets — Matches Crypto Briefing headline 'Iran strikes US bases in Bahrain and Kuwait as Middle East conflict rattles crypto markets'; cited to Crypto Briefing.
• The exchanges landed as NATO leaders convened — Supported by CNN headline ('as NATO leaders meet') and CNBC 'Dispatch from NATO'; cited to CNN.
• CNBC noted the Iran escalation competes for leaders' attention at a summit dominated by security concerns — CNBC source is only a headline/teaser ('Dispatch from NATO, U.S. strikes Iran'); the framing about competing for attention is plausible but not established by the snippet.
• The Times of India said the region was again on the brink of war — Matches ToI headline 'Middle East on brink of war again as US-Iran trade strikes'; cited to ToI.
• The sanctions target Tehran's principal revenue source / cap war financing — Article explicitly frames this as a hypothesis with intent 'inferred, not confirmed'; sources confirm oil is blocked but not Washington's rationale.
• Iranian strikes draw Gulf states directly into the exchange — Reasonable inference from the Bahrain/Kuwait strikes per Crypto Briefing, but the 'drawn directly into the exchange' framing is analysis not stated in the source snippet.
• Casualty figures, scale of strikes, and formal justification are unconfirmed — Correctly caveated; none of the headline-level sources provide these details, so flagging them as unconfirmed is accurate.
