A grim mix of accountability, public health alarm and strategic strain leads the world news today. In Los Angeles, Kenneth Iwamasa, Matthew Perry’s former assistant, was sentenced to 41 months in prison for his role in the actor’s ketamine overdose death, closing out the federal case against five defendants. In East Africa, Uganda has shut its border with Congo in an urgent bid to contain a worsening outbreak of a rare Ebola strain, as deaths mount and cross-border transmission fears grow. In Washington, a new CSIS analysis warns that although the US can still meet any likely military scenario involving Iran, rebuilding the advanced munitions used in that conflict could take years, exposing a potential gap in readiness. Elsewhere, Australia’s ABC is suddenly searching for new editorial leadership after news director Justin Stevens resigned, while London firefighters battle a major blaze near a kosher supermarket in Golders Green.
