The United States, finding reports of Russian military movements on Ukraine's border credible, asked Moscow to explain the "provocations" and is ready to engage on the situation, the U.S. State Department said Monday.

State Department spokesman Ned Price told a news briefing that the United States would be concerned by any effort by Moscow to intimidate Ukraine, whether it occurred on Russian territory or within Ukraine, VOA reported with reference to Reuters.

"We've asked Russia for an explanation of these provocations," Price said. "But more importantly, what we have signaled with our Ukrainian partners is a message of reassurance."

In turn, White House press secretary Jen Psaki told reporters that "recent escalations of Russian aggression and escalation in eastern Ukraine" is "something we're watching closely."
