Russia-Ukraine war live: Biden to meet Nato secretary in Poland; Russian military responds to Wagner chief’s ‘treason’ claim

More now on Biden’s meeting today with the Bucharest Nine. Most members of the group – made up of the countries on Nato’s eastern flank who joined the western military alliance after being dominated by Moscow during the cold war – are strong supporters of military aid to Ukraine, and officials from countries in the group have called for additional resources such as air defence systems.

At the meeting, Biden plans to reaffirm commitments over their security and discuss support for Ukraine before he returns to Washington.

Russia regards Nato, which could soon expand to include Sweden and Finland, as an existential threat.

Lithuanian President Gitanas Nauseda’s message to Biden will be that it wants “greater involvement of the US in Europe, Nato’s eastern flank and, of course, more aid to Ukraine,” his chief foreign policy adviser told Lithuanian radio on Tuesday.

“Lithuania and other like-minded countries have several requests, which concern air defence, forward defence presence, air defence systems, and greater investments in the defence industry,” Asta Skaisgiryte said.

The former Soviet republic on Russia’s doorstep joined Nato in 2004 and plans to host Biden in July for the security alliance’s leaders’ summit.
