The United States is watching “very closely” “whether Russia might be crossing the line in any way, the intervention line,” White House spokesman Jay Carney says at his daily briefing.
“Ukraine territorial integrity needs to be respected,” Carney said. “Ukrainian sovereignty needs to be respected. And it would be a grave mistake to intervene.”
“We are concerned about reports of Russian intervention or of aggression,” Carney says. “We evaluate this... in a variety of ways,” in partnership with allies and in direct communications with Ukrainian and Russian officials, he says. “Obviously there are various conversations happening in real time with regard to this very fluid situation.”
