The US is pulling its B-1 bombers out of a UK base after a suspected plot and arrests there, a sign of how shaky the Middle East standoff has become.

• American B-1 bombers are leaving their UK base over security worries after five men were arrested near it last week.
• Hostilities are widening: Israel is still hitting the West Bank, Gaza and Lebanon, while Yemen's government, backed by Saudi Arabia, launches a new offensive against the Houthis.
• Iran says there is no military answer to the conflict and warns its response would be stronger next time, while asking for talks.
• Oil is the pressure point — Brent is sitting above $100, and diesel is tight, with the White House blaming Ukraine, China and California rather than the strikes on Iran.
• Mortgage rates just had their biggest weekly jump in four years and are above 7%, even as the administration insists the economy is booming.

Outlook: Expect more fighting and high oil prices in the near term, with any relief depending on talks that neither side looks ready for.
