The claim that the US stated it would take six months to clear mines laid by Iran is not directly supported by the provided evidence. The evidence for this claim is drawn from general Wikipedia entries about the 2026 crisis, but none of the search results or cross-references contain the specific timeline or statement regarding a six-month clearance period.

The evidence indicates that Iran's actions regarding the strait's closure are linked to the US/Israel conflict starting on February 28, 2026, and that the closure is a major weapon for Iran. However, none of the provided sources explicitly state that the closure occurred *following* strikes that killed Ayatollah Ali Khamenei, making the specific causal link and the death of the Supreme Leader unverified by the evidence provided.

The evidence confirms the US is involved in actions concerning ships in the Gulf and Indo-Pacific related to the conflict. However, none of the provided search results or cross-references contain the specific claim that the US 'captured or turned back ships linked to Iran' in both regions, nor does it confirm Tehran's specific denouncement of these actions as 'piracy' in the context of the evidence provided.

The evidence shows that Iran previously allowed passage to certain nations (like India, Pakistan, etc.) and that Iran later announced opening the strait to all ships except those associated with 'enemies of Iran.' This supports the idea of a change in policy regarding passage, but the specific detail about closing it *only* until the US lifts a blockade is not corroborated by multiple sources.

The evidence confirms that Iran has made statements regarding the status of the strait, including opening it to certain ships. However, the specific detail that Iran 'published a map showing mined sections... and an alternative route for approved ships earlier this month' is not explicitly confirmed by multiple sources, although the general theme of Iran controlling information about passage is present.
