UK police arrested several men on explosives charges next to the US bomber base at RAF Fairford, a bad sign that the war with Iran is reaching British soil.

• Counterterrorism police took over the case after cars believed to hold explosives were found near the base.
• Homes in the nearby village were cleared out overnight while a bomb disposal team checked the vehicles.
• Fairford matters because US B-52 and B-1 bombers have been flying missions against Iran from there, pulling the UK into the fight.
• Iran says it has now seized a second American underwater drone in the Strait of Hormuz and is pulling data off it.
• Iran's military is warning that if it cannot trade through Hormuz, nobody will — a threat to shut the waterway for everyone.

Outlook: Expect more security alerts around bases supporting the Iran campaign, and no quick end to the fighting while Iran claims it has already won.
