Ukraine’s Foreign Minister Dmytro Kuleba called for a NATO summit to stop Russian attacks and repeated his request to send fighter jets to the country, The Guardian reports.

He wrote on Twitter: “Ukraine confirms its full solidarity with Poland and is ready to provide any necessary support. The collective response to Russia’s actions must be tough and principled.

“Among the immediate actions: a NATO summit with Ukraine to develop new joint actions to force Russia to reverse its course of escalation, supplying Ukraine with modern aircraft such as the F-15 and F-16, as well as air defense systems so that we can intercept any Russian missiles. Today, defending the skies of Ukraine means defending NATO,” Kuleba wrote.

Poland is considering the possibility of activating Article 4 of the NATO Treaty

According to Polish government spokesman Piotr Mueller, authorities in Warsaw are debating whether to request Article 4 consultations.

Article 4 provides that: “The Parties shall consult whenever, in the opinion of either Party, the territorial integrity, political independence or security of either Party is threatened.”

The 30 member states then begin formal consultations at the request of the threatened member. During discussions, it is analyzed whether there is a threat and how to counter it, and decisions are made unanimously.

However, Article 4 does not mean that there will be direct pressure to act.

This consultation mechanism has been launched several times in the history of NATO. An example can be a year ago, when Turkish soldiers were killed during an attack from Syria.

In this case, NATO decided to hold consultations, but did not take any action.

Two rockets fell on the territory of Poland on the border with Ukraine, two people died as a result of the explosion. US intelligence sources told AP that they were two stray Russian missiles.

The Pentagon has not yet confirmed the information. At the same time, President of Ukraine Volodymyr Zelenskyi said that the missiles are Russian. Moscow denies the attack.
