NATO Secretary General Jens Stoltenberg confirmed one of the alliance's top priorities is to provide more air defense systems to Kyiv, after Russia launched its biggest wave of missile attacks on Ukrainian cities in more than a month on Tuesday.
"Our main priority now or one of the top priorities now is to provide more air defense systems for Ukraine," Stoltenberg said.
Stoltenberg added he has spoken with Polish President Andrzej Duda and US President Joe Biden, after a missile landed in eastern Poland on Tuesday and killed two people near the border with Ukraine.
The NATO chief said in the same news conference that preliminary analysis suggests the Poland missile incident was "likely" caused by a Ukrainian air defense missile, adding: "This is not Ukraine's fault. Russia bears ultimate responsibility, as it continues its illegal war against Ukraine."
The explosion marked the first time a NATO country has been directly hit during Russia's invasion of Ukraine, with global leaders working to allay fears of a potential escalation in the conflict as a result of the strike.
"We agreed that we need to stay vigilant, calm and closely coordinated. We will continue to consult and monitor the situation very closely," Stoltenberg said.
"NATO stands united, and we will always do what is necessary to protect and defend all allies."
