The Ukrainian military said the four were killed in a mortar attack it blamed on Russian troops.
Milley's office announced his calls to his Russian and Ukrainian counterparts but provided no details.
Kirby said it was safe to assume that Milley raised U.S. concerns about escalating tensions and cease-fire violations.
