According to United States intelligence officials, Russia is planning to carry out a full-scale invasion of Ukraine sometime over the course of the next 48-hours.

“The President of Ukraine has been warned Russia will highly likely begin an invasion within 48 hours based on U.S. intelligence,” the U.S. official told Newsweek , going to add that “reporting from aircraft observers indicates Russia violated Ukrainian airspace earlier today, flying possible reconnaissance aircraft for a short period over Ukraine.”

However, the source said that “it’s possible for sure,” because “Putin can’t keep so many troops in the field much longer.”

The U.S. intelligence official said that the assessment includes Russian airstrikes, cruise missiles and a ground invasion, as well as a major thrust toward the capital Kyiv from the northern border with Belarus, where the Russian military recently held joint exercises with their ally, according to Newsweek.

The source indicated, however, that daily developments could alter Moscow’s plans.

A second U.S. official said that a ground invasion, most likely at night, would be preceded by a cyberattack.

Just a little while after Newsweek was made aware of these assessments by American intelligence, websites for Ukraine’s Defense Ministry, Foreign Ministry, and other institutions within the country went totally offline in what could potentially be some kind of cyberattack.

“Another source who participated in a National Security Council call on Tuesday confirmed to the publication the White House was ‘incredibly pessimistic’ about the Kremlin’s military operation being limited to the Russia-backed rebel republics and that an invasion would likely take place within 24 to 48 hours,” Newsmax reported.
