"The security situation in Ukraine continues to be unpredictable due to the increased threats of Russian military action and can deteriorate with little notice. U.S citizens in Ukraine should consider departing now using commercial or other privately available transportation options," read the statement issued by the Embassy.

"U.S. citizens wishing to depart Ukraine by land have several options. However, due to ongoing COVID-19 restrictions, U.S. citizens should be prepared to comply with country-specific entry requirements, which may differ from the entry requirements for travelers arriving by plane," read the statement.

The embassy suggested that citizens go to countries near Ukraine, which includes Poland, Slovakia, Hungary, Romania, and Moldova.

However, it is not recommended to enter Moldova "through the breakaway region of Transnistria," as in this case, the diplomatic mission will be unable to provide citizens with full assistance.

Those American citizens, who are currently facing difficulties buying tickets for commercial flights, can be granted a loan at the embassy, according to the statement.

Russia has rejected all accusations of its alleged preparations for invasion of Ukraine and stated that it has no intention to attack any country.
