Security, accountability and disruption shaped world news today. In Washington, the man accused of trying to assassinate President Donald Trump at last month’s White House Correspondents’ Dinner pleaded not guilty to four federal charges, moving a politically explosive case toward trial. Elsewhere in the U.S. capital, a new clash over secrecy erupted as Defense Secretary Pete Hegseth asked Pentagon lawyers to review whether Senator Mark Kelly improperly disclosed classified information when discussing U.S. weapons stockpiles, an allegation Kelly rejects. The wider fallout from conflict in the Middle East is also showing up far from the battlefield: Heathrow says April passenger traffic fell as war-related uncertainty dampened international travel. In Australia, police say they have found a body believed to be that of fugitive Julian Ingram, wanted over a January triple killing. And in Italy, a far calmer headline: a trade show debut for a “tapeless” zipper billed as a greener industrial innovation.
