According to CNN, US national security adviser Jake Sullivan warned Americans in Ukraine on Friday to leave within one to two days, spelling out what a Russian attack on the country could look like -- and that civilians could die.
"Any American in Ukraine should leave as soon as possible, and in any event in the next 24 to 48 hours," Sullivan said. "We obviously cannot predict the future, we don't know exactly what is going to happen. But the risk is now high enough and the threat is now immediate enough that this is what prudence demands."
"If a Russian attack on Ukraine proceeds, it is likely to begin with aerial bombings and missile attacks that could obviously kill civilians without regard to their nationality. A subsequent ground invasion would obviously involve the onslaught of a massive force."
