Despite renewed calls for air support from Ukrainian officials, US President Joe Biden has ruled out sending F-16 fighter jets to Ukraine.
Asked by a reporter on Monday if the US would be providing the planes, Mr Biden replied simply “no”.
His remarks come just one day after Germany’s leader ruled out sending fighter jets.
Ukraine has stated that the jets are required to take control of its airspace in the ongoing conflict with Russia.
F-16 Fighting Falcons are widely regarded as one of the most dependable fighter jets in the world, and are used by countries such as Belgium and Pakistan.
They would be a significant upgrade over Ukraine’s current Soviet-era fighting jets, which were built before the country declared independence from the USSR more than 30 years ago.
However, Mr. Biden has repeatedly turned down Ukraine’s request for the jets, preferring to focus on other areas of military support.
The United States announced last week that it would supply Kyiv with 31 Abrams tanks, with the United Kingdom and Germany also pledging similar assistance.
Andrii Melnyk, Ukraine’s Deputy Foreign Minister, welcomed the announcement but asked allies to form a “fighter jet coalition” to provide Ukraine with Eurofighters, Tornados, French Rafales, and Swedish Gripen jets.
