Strait of Hormuz31 Mar 2026 11:30
From the BBC's rolling live coverage:
"Former naval commander Tom Sharpe says he doesn't think the Strait of Hormuz, one of the world's busiest oil shipping channels, can be opened with force like the US is threatening.
Unless Iran agrees to stop attacking boats who pass through, using force is "unlikely to work", Sharpe tells BBC Radio 4's Today programme.
"Iran have control of this situation, I think that much is clear, and I think they will continue to do so going forward," Sharpe says, adding it's not in their interest to change this.
He adds that it comes down to Iran and what they choose to do in the next weeks or months".
Trump and his colleagues have some thinking to do.
