US diplomats reached out to Russian counterparts in "real time" to discuss security concerns during the Wagner mercenary group revolt, the White House says. "We had good direct communications with the Russians over the course of the weekend, it’s our expectation that that would be able to continue going forward," says John Kirby, White House national security spokesman during a press briefing. Kirby adds US officials continue to monitor Moscow's nuclear posture during the invasion by Russian troops of pro-Western Ukraine and that they've "seen no indication that there's any intent to use nuclear weapons inside Ukraine."
