Claim 1: “President Donald Trump also said Iran had attacked ships.”
SINGLE SOURCE
Only one cross-reference source (The Guardian) is provided, stating that Trump suggested an attack against Kharg Island if Iran fired on US ships. This is insufficient for corroboration.
compare_arrows
cross reference SUPPORTS — Trump has suggested an attack against Kharg Island as far back as the 1980s, when he told the Guardian he would 'do a number on Kharg Island; I’d go in and take it' if Iran fired on US ships.

Claim 2: “Iran declared the strait closed again, and dozens of commercial ships that tried to exit the strait turned back around and remain trapped west of the crucial passage.”
CORROBORATED
Two web search results indicate a pattern of Iran's actions regarding the strait's status: one mentions Iran opening it and then closing it, and another mentions the strait being 'largely blocked by Iran.' This supports the narrative of closure.

Claim 3: “S&P 500 futures dropped nearly 0.8%, Nasdaq 100 futures fell 0.7%, and Dow futures tumbled 500 points, or 0.7%. Russell 2000 futures slid 1.4%.”
SINGLE SOURCE
While multiple web search results discuss market movements (e.g., one mentions Dow futures plunging by 517 points, or 1.1%, and S&P 500 futures falling about 1%), the specific figures cited in the claim (S&P 500 futures dropped nearly 0.8%, Nasdaq 100 futures fell 0.7%, Dow futures fell 500 points, or 0.7%, and Russell 2000 futures slid 1.4%) are not consistently corroborated across the provided web search results. The evidence is suggestive but not fully corroborative for all listed percentages.
