BAKHMUT, Ukraine (AP) – Ukrainian authorities say that workers have pulled scores of bodies from smashed buildings in the devastated city of Mariupol in an “endless caravan of death.” At the same time, fears of a global food crisis are escalating over Ukraine’s inability to export millions of tons of grain through its blockaded ports. Ukrainian and Russian forces are also continuing to battle for control of a key eastern city in the industrial heartland known as the Donbas. An analyst said that the Kremlin’s continued advances could eventually open up the possibility of a negotiated settlement between the two nations.
