A volatile holiday weekend stretched from New York to Tehran and Eastern Europe. In Brooklyn, the Fourth of July was punctuated first by a brief fire on the Brooklyn Bridge after the fireworks display, then by a mass shooting near Coney Island that left eight people wounded, including four children, with one young woman critically injured. In Britain, a 22-year-old woman died after a skydiving incident near Nottinghamshire’s Langar Airfield, prompting an investigation into what went wrong. In Tehran, the funeral for Iran’s late Supreme Leader turned sharply incendiary as a performer publicly called for Donald Trump’s death amid anti-American chants from a vast crowd. And on the diplomatic front, Trump sought to cast himself as a mediator, offering in separate calls with Vladimir Putin and Volodymyr Zelenskyy to help broker a political settlement to the war in Ukraine, though the gulf between Moscow and Kyiv remains wide.
