WATCH: White House urges Americans in Ukraine to leave country

White House press secretary Jen Psaki on Wednesday repeated warnings made earlier by President Joe Biden that Americans in Ukraine should leave the country.

Psaki said the State Department had assessed in October that around 6,600 Americans were in the country at that time.

U.S. officials say that with more than 100,000 Russian troops nearing Ukraine’s eastern and northern borders, the threat of a Russian invasion is more serious than others that have come and gone during the years of fighting between the Russia-backed rebels and Ukrainian forces.

President Joe Biden had said “it would be wise” for Americans other than essential diplomats to leave Ukraine and has ordered the deployment of 1,700 troops to neighboring Poland.

Psaki said the situation facing Americans inside Ukraine was not similar to the mass evacuation after the fall of Kabul in Afghanistan.

Psaki was also asked about reports that Russian President Vladimir Putin made a rape joke about Ukraine.

“Any joke about rape would certainly be something that everyone in this government would be outraged by,” she said. “I’d also note that we have never held back in our concern about the lack of truthfulness of some of the statements that come out of the mouth of President Putin and members of the Russian leadership, and also the bellicose rhetoric that has come out of their mouths.”

After Iran unveiled a new missile on Wednesday with a reported range that would allow it to reach both U.S. bases in the region as well as targets inside its archfoe Israel, Psaki said Iran nuclear talks were at a “pivotal moment.”

Iran State TV reported that the missile uses solid fuel and has a range of 1,450 kilometers (900 miles). It is called the Khaibar-buster, a reference to a Jewish castle overrun by Muslim warriors in the early days of Islam.

The report comes as negotiations continue in Vienna to revive Tehran’s tattered nuclear deal with world powers. Iran, which has long said it does not seek nuclear weapons, insists its missile program is only a deterrent.
