The U.S. Embassy in Kyiv received information about a "potential significant airstrike" and has suspended its operations.

The U.S. State Department has announced that the Washington embassy in Kyiv received information regarding a “potential significant airstrike” that was expected to occur on Wednesday.

“As a precaution, the embassy will be closed, and staff have been advised to seek shelter,” the message published on the embassy's website on X stated.

The ministry also urged U.S. citizens residing in Ukraine to immediately take cover in shelters and monitor local media in the event of an air raid alert.

As noted by Reuters, the warning was issued a day after Kyiv utilized American ATACMS missiles to strike a Russian ammunition depot in the Bryansk region, approximately 130 km from the Ukrainian border.

A source at the U.S. embassy informed “Interfax-Ukraine” that the suspension of the U.S. embassy's operations in Kyiv is related to the Russian threat of a combined missile-drone attack, rather than a change in the Kremlin's nuclear doctrine.

“The embassy's closure is linked to the air raid alert, including an increased potential threat of a combined missile-drone attack, as has occurred recently. We continue to monitor the situation while working with our Ukrainian partners,” the source stated.

The embassies of Greece and Spain in Kyiv announced that they would remain closed on Wednesday for security reasons. The Greek diplomatic mission advised its citizens to avoid unnecessary travel and to stay in safe places.

The Romanian embassy reported that, “considering the developments in the security situation in Ukraine,” it has taken additional measures to protect its staff and limited its operations to essential tasks.

The Polish embassy in Kyiv is operating as usual, albeit with security measures in place, reported PAP head of the institution Piotr Lukasiewicz.

“We take these warnings very seriously; however, I am on-site myself, and some staff are in secure locations,” he stated.

Meanwhile, Ukraine's military intelligence (HUR) stated on Wednesday that a message was circulated on social media purportedly on behalf of the agency, warning of a threat of “particularly massive” missile strikes across cities in Ukraine. The agency emphasized that this message is false and constitutes a coordinated Russian disinformation campaign.

“This message is a fake; it contains grammatical errors typical of Russian information-psychological operations. We urge everyone to trust information only from official sources and from spokespeople of the HUR of the Ministry of Defense,” HUR called out.

Background. As reported, on Tuesday, Russian dictator Vladimir Putin approved a amendment to the nuclear doctrine stating that the use of nuclear weapons by Moscow will be based on a “critical threat” to the sovereignty and territorial integrity of Belarus and Russia, which now includes strikes against Russia with long-range weapons.
