A grim and volatile day in world news is led by Britain, where police in Devon and Cornwall have opened a murder inquiry into the death of former minister and ex-MP Ann Widdecombe, whose long political career and later celebrity made her one of the UK’s most recognizable public figures. In the Middle East, tensions between Washington and Tehran have sharpened again after reports that Israel warned the U.S. of an alleged new Iranian plot to assassinate President Trump, intelligence American officials are still assessing. Elsewhere, Europe has been rattled by two stark travel and climate emergencies: a Ryanair flight was forced into an emergency landing in Greece after a cabin window reportedly detached midair, injuring a passenger, while deadly wildfires in southern Spain have killed at least 11 people, with four Britons feared among the dead as authorities search for the missing.
