NATO Secretary General Jens Stoltenberg says there needs to be a “consensus” among all allies regarding Ukraine's accession to NATO, Paralel.Az reports citing BBC.

Stoltenberg says it is too early to tell when that will happen, adding that they are constantly working with Ukraine on bringing it “closer to NATO” to enable its accession when the time comes.

He expects allies to agree to a substantial assistance package for Ukraine saying the aid would serve as a bridge to Kyiv's membership.

He adds that there is a constant threat of cyber-attacks and sabotage against NATO allies from Russia, but that those fall short of military attacks.

"We need to be vigilant," Stoltenberg says.

Asked about NATO's help to Ukraine’s air defence, Stoltenberg says the US, Germany, Italy, the Netherlands and Romania are partnering to donate Patriot missile batteries and other systems to aid Ukraine, adding they were always looking at how they could “do more”.

On deepening cooperating with South Korea, NATO's secretary general says that the war in Ukraine shows how “our security is interlinked”, adding that "what happens in Europe matters for Asia" and vice versa.
