Earlier this week, NATO Secretary-General Jens Stoltenberg paid an unannounced visit to Kiev which marks his first visit since the Russian invasion. 

Stoltenberg invited Ukrainian President Volodymyr Zelensky earlier this month to the NATO summit in July and also announced that NATO member states have provided 65 billion euros ($70 billion) in military aid to Kiev in light of the ongoing war in Ukraine.

Stoltenberg also welcomed the start of deliveries of Western tanks and other armored vehicles to Ukraine. "This can make a real difference on the front lines," he underlined.

Yesterday, Stoltenberg announced that NATO allies have all agreed that Ukraine should become a member of the alliance.
